Sixty-four fiberoptic bronchoscopic examinations were performed for 58 patients with Hodgkin's and non-Hodgkin's lymphomas and radiographically evident pulmonary abnormalities. Diagnoses were obtained in 23 cases (36%). Examination of 12 lung biopsy specimens showed lymphoma and one, squamous cell carcinoma. Six patients had pneumocystis carinii; 2, aspergillosis; 1 cryptococcosis; and 1, herpes simplex infection. It is recommended that fiberoptic bronchoscopy be the first invasive procedure employed in the evaluation of pulmonary parenchymal abnormalities in patients with Hodgkin's and non-Hodgkin's lymphomas.

53 patients with advanced and measurable cancerr were treated with vindesine in doses of 3 mg/m2 (pretreated) and 4 mg/m2 (non pretreated) i.v. once weekly. 48 patients are evaluable for response: of 14 patients with squamous cell carcinoma of the lung, 1 partial remission (PR), 1 minor response (MR) and 1 no change (NC) were observed. In 5 patients with large cell carcinoma of the lung: 1 NC. In 3 with adenocarcinoma of the lung: 1 MR. One patient with nasopharyngeal carcinoma had progressive disease. Stable disease was observed in a patient with carcinoma of the tongue and in a patient with adenocarcinoma of the esophagus. Four patients with colorectal carcinoma had progressive disease. One MR was observed in a patient with breast cancer, while all of the other 3 patients had progressive disease. One carcinoma of the penis was stable. One MR was observed in a patient with Hodgkin's disease. One PR was observed in a case with no-Hodgkin's lymphoma. A patient with acute leukemia had progressive disease. Among 9 patients with malignant melanoma, 3 had an MR and 1 patient had stable disease. A patient with fibrosarcoma had progressive disease. Observed toxicity included leukopenia, thrombocytopenia, anemia, paresthesias, constipation, jaw pain, nausea, stomatitis, alopecia, loss of taste, pruritus and skin rash, weakness and fatigue.

In order to ascertain the frequency and distribution of isochromosomes in neoplasia, we surveyed the cytogenetic data from 20,007 tumors with clonal chromosome aberrations reported in the literature. Tumor types for which at least 50 cases with acquired aberrations and 10 cases with isochromosomes had been reported were selected, yielding a total of 18,160 neoplasms. Of these, 1,792 cases (9.9%) displayed a total of 2,014 isochromosomes. The 9 most common isochromosomes (detected in at least 50 cases) were, in decreasing order of frequency, i(17q), i(8q), i(1q), i(12p), i(6p), i(7q), i(9q), i(5p), and i(21q). The frequency of isochromosomes varied among the different tumor types, with the highest incidence in germ cell neoplasms (60%) and the lowest in chronic myeloproliferative disorders (2.3%). Also, the spectrum of isochromosomes differed among the neoplasms. The most common isochromosomes in the different tumor types were i(11q), i(17q), and i(21q) in acute myeloid leukemia; i(9q), i(17q), and i(22q) in chronic myeloid leukemia; i(17q) in chronic myeloproliferative disorders; i(X)(q13), i(17q), and i(21q) in myelodysplastic syndromes; i(7q), i(9q), and i(17q) in acute lymphoblastic leukemia; i(1q), i(7q), i(8q), and i(17q) in chronic lymphoproliferative disorders; i(1q), i(6p), i(9p), i(17q), and i(21q) in Hodgkin's disease; i(1q), i(6p), and i(17q) in non-Hodgkin's lymphoma; i(1q), i(8q), and i(17q) in adenocarcinoma; i(1q), i(3q), i(5p), and i(8q) in squamous cell carcinoma; i(5p), i(8q), and i(11q) in transitional cell carcinoma; i(1q), i(7q), and i(17q) in Wilms' tumor; i(1q), i(12p), and i(17q) in germ cell neoplasms; i(1p), i(1q), i(6p), and i(17q) in sarcoma; i(5p), i(6p), i(7p), and i(21q) in mesothelioma; i(1q), i(6p), and i(17q) in malignant neurogenic neoplasms; i(1q), i(6p), and i(17q) in retinoblastoma; and i(1q), i(6p), and i(8q) in malignant melanoma.

We reviewed the clinical and fine-needle aspiration (FNA) findings in 20 patients with poorly differentiated carcinomas presenting initially as parotid or as submandibular masses. There were 11 primary tumors and nine metastatic malignancies in 14 males and six females ranging in age from 39 to 89 yr (median = 66). The tumor types included three primary carcinomas with oncocytic features, three additional cases of high-grade parotid carcinoma, one case of primary neuroendocrine carcinoma, two examples of malignant mixed tumor, one high-grade mucoepidermoid carcinoma, and a single example of malignant lymphoepithelial lesion. Six patients with metastatic carcinoma had previous diagnoses of malignancy. In the three remaining individuals, primary carcinomas of the lung (two cases), and an unknown primary site presented initially as parotid masses. Five examples of metastatic squamous cell carcinoma, one metastatic basal cell carcinoma, and two metastatic renal cell carcinomas were identified. One parotid lymphoepithelioma was interpreted cytologically as an atypical lymphoproliferative process suggestive of Hodgkin's disease. Nineteen cases (95%) were correctly classified as carcinoma at the time of FNA. High-grade carcinomas aspirated from the parotid may be primary, but are frequently metastatic to either the gland, or to an intraparotid lymph node. Our experience indicates that some metastatic carcinomas present at this site, without a previous history of malignancy. Distinguishing primary from metastatic lesions has important therapeutic implications.

Non-Hodgkin lymphoma (NHL) is the second most frequent malignant tumor in the head and neck, squamous cell carcinoma being the most frequent. NHL often appears in extranodal localisations. In the head and neck, two distinct extranodal sites are recognised: extranodal lymphatic localisations or involvement of the ring of Waldeyer, and extranodal extralymphatic localisations. In this study we reviewed the imaging features of 55 patients who showed extranodal NHL-localisations to investigate whether we could find specific imaging characteristics. There are no pathognomonic signs. However, if more than one extranodal mass is detected, if the mass appears huge without necrosis or ulceration, if the mass is associated with large, non-necrotic nodes, the diagnosis of non-Hodgkin lymphoma can be suggested; however, it is usually not possible to exclude other pathological processes with absolute certainty.

We describe the clinical and histopathological findings of a conjunctival squamous cell carcinoma occurring in a patient with acquired immunodeficiency syndrome (AIDS). The excisional biopsy specimen disclosed a papillar, well differentiated and mature squamous cell carcinoma with microinvasion. The biopsy was studied for the presence of Human papilloma virus DNA by using in situ hybridization but no signal was demonstrated in any part of the tumour. Although Kaposi's sarcoma and non-Hodgkin's lymphomas are the most common malignancies reported in AIDS, squamous cell carcinomas may be encountered in the disease. Underlying infection with the human immunodeficiency virus should be considered when conjunctival localization of such malignancies is observed.

We have identified the nucleotide sequence of the cDNA encoding the human counterpart of the mouse gene Plk (polo-like kinase). The sequence of the human gene, PLK, predicts a serine/threonine kinase of 603 aa. Expression of PLK mRNA appeared to be strongly correlated with the mitotic activity of cells. Resting peripheral lymphocytes did not express the gene at all. When primary T cells were activated by phytohemagglutinin, a high level of PLK transcripts resulted within 2-3 days. In some cases, addition of interleukin 2 to these cells increased the expression of PLK mRNA further. In contrast, primary cultures of human peripheral macrophages, which were not dividing under the culture conditions applied, showed very little or no PLK mRNA. Stimulation of these cells by bacterial lipopolysaccharide, an inducer of several cytokines in macrophages, totally abrogated the expression of PLK mRNA. In line with a function of PLK mRNA expression in mitotically active cells is our finding that six immortalized cell lines examined expressed the gene. In A-431 epidermoid carcinoma cells this expression was down-regulated by serum starvation and enhanced after serum was added again. Tumors of various origin (lung, colon, stomach, smooth muscle, and esophagus as well as non-Hodgkin lymphomas) expressed high levels of PLK transcripts in about 80% of the samples studied, whereas PLK mRNA was absent in surrounding tissue, except for colon. The only normal tissues where PLK mRNA expression was observed were colon and placenta, both known to be mitotically active. No PLK transcripts were found in normal adult lung, brain, heart, liver, kidney, skeletal muscle, and pancreas. In Northern blot experiments with RNA from lymphocytes which were treated with phytohemagglutinin and cycloheximide, PLK transcripts were not detectable, suggesting that PLK is not an early growth-response gene.

A subset of Hodgkin's disease (HD) and breast cancer patients have been reported to have elevated hprt mutant frequencies in peripheral blood lymphocytes after cessation of therapy. A subset of these patients are also known to develop second therapy-related malignancies. Therefore, it is clearly important to determine if these elevations in mutant frequency represent true, persistently elevated mutation frequencies. As a follow-up to our study of patients previously treated for HD, we recruited for a prospective study six previously treated HD patients and five patients who had been treated for squamous cell carcinoma of the head and neck. These individuals were studied several times over a 6-7 months. The results confirmed that a subset of patients have persistently high mutant frequencies when compared to 71 previously studied controls. The study was designed to determine if the elevated mutant frequencies of treated patients represented independent mutations or resulted from the in vivo expansion of single mutant cells. We used the polymerase chain reaction to examine DNA single strand conformation polymorphisms at the T-cell receptor-gamma locus of individual mutant clones. This analysis showed that 20.1% of the mutants from Hodgkin's disease patients and 17.5% of the mutants from squamous cell carcinoma patients were siblings. The sibling mutants generally did not persist over time. However, one patient had one mutant clone that persisted, but slowly decreased in prevalence over a 7 month sampling period. The data demonstrate that treatments for cancer result in persistently elevated mutation frequencies at the hprt locus in some, but not all, patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Forty-five patients with oral or pharyngeal swellings were subjected to fine needle aspiration cytology (FNAC) of the mucosal surface over eight years. The age of the patients ranged from 2 to 85 years. The male:female ratio was 25:20. The common sites of involvement were palate (16 cases), cheek (9), pharynx (7) and tonsillar/peritonsillar area (6). Tongue, maxilla, alveolus and lips were less frequently involved. FNAC played an important role in differentiating inflammatory from neoplastic lesions and also benign from malignant neoplasms. Fifteen cases were cytologically diagnosed as benign neoplasms and included pleomorphic adenoma (11 cases), schwannoma (2), odontogenic tumor (1) and benign neoplasm not otherwise specified (1). Sixteen cases were diagnosed as malignancies. There were seven cases of malignant salivary gland tumors and 6 of squamous cell carcinoma. Two cases were high grade non-Hodgkin's lymphomas, and one was malignant odontogenic tumor. Of the 11 inflammatory or reactive lesions, 4 were found to be harboring Actinomyces. The rate of inadequate sampling was 6.7%. Histopathology reports on excised tissue were available for 10 cases only. Seven of nine cases with adequate cytology (77.88%) showed complete agreement with histology.

We describe two unusual cases of squamous cell carcinoma of the uterine cervix associated with prominent intratumoral deposition of amyloid. Most of the amyloid is deposited within and between the tumor islands, but some amyloid globules are intracellular. The amyloid shows immunoreactivity for keratin, suggesting that it is derived from cytokeratin intermediate filaments, similar to the pathogenesis of primary cutaneous amyloidosis. Tumor-related amyloidosis is a heterogeneous but distinctive subgroup of amyloidosis, including cytokeratin-derived amyloid deposited within squamous or squamous-related tumors as in the present cases, polypeptide-derived amyloid associated with endocrine tumors, and systemic inflammation-associated amyloid (AA protein) as observed rarely in Hodgkin's disease and renal cell carcinoma.
