The authors report four patients whose initial symptom of tumor recurrence or progression was unilateral numbness of the chin. Two patients had Hodgkin lymphoma, one had malignant melanoma, and one had prostate cancer. Physical examination was notable only for unilateral anesthesia of the chin and lower lip. Diagnostic evaluation, including computed tomography (CT) scan and magnetic resonance imaging (MRI) of the brain, plain radiographs of the mandible, and cerebrospinal fluid analysis for protein, glucose, and cytology were normal. Bone scans revealed osseous lesions in the axial skeleton of all patients, whereas only two patients had abnormal uptake in the mandible. The authors conclude that in the setting of a negative evaluation for central nervous system (CNS) or local mandibular disease, mental neuropathy is associated with recurrent or progressive skeletal disease. In addition, to document relapsed or progressive cancer, the skeletal system may have to be examined at sites distant from the mandible.

A Thoroughbred stallion developed priapism that was unresponsive to medical treatment and lavage of the corpus cavernosum penis with heparinized 0.9% NaCl solution. Three weeks after onset of priapism, the penis was firm and noncompliant, and penile pain sensation and ability to retract the penis were lost. Ultrasonography confirmed thrombosis of the corpus cavernosum penis. The stallion was euthanatized because of poor prognosis for return to breeding soundness. Necropsy revealed enlargement of numerous lymph nodes. The dorsal penile nerves were demyelinated distal to the crura of the penis. A diagnosis of generalized malignant melanoma was made; however, neither metastasis to the vertebral canal nor compression of spinal nerve roots as they exited the vertebral foramen was found. Priapism is a persistent erection without sexual arousal and is initially unassociated with penile paralysis, but if prolonged, leads to irreversible venous occlusion where collecting veins join the cavernous spaces. Damage to the dorsal penile nerves may explain the long-term penile paralysis and loss of sensation that accompanied priapism in this stallion. Priapism unassociated with the use of phenothiazine-derivative tranquilizers is uncommon in horses.

A case of lentigo maligna melanoma on the vermilion of the right lower lip which invaded deeply along the mental nerve is described. The patient also had sensory loss and numbness in the area innervated by the mental nerve, which was the only sign of this rare mode of invasion in this case. Early excision of the lentigo maligna lesion is stressed, and if the patient complains of sensory disturbances in the area of the lesion, this might be a sign of deep invasion of the tumour along the nerve bundle.

A Phase I study of interferon alfa-2a was conducted in 20 patients with disseminated cancer to establish the relationship between dose and interferon-related side effects. Fever was the most common side effect, and was not dose-related. Other side effects not related to dose included flu-like symptoms, gastrointestinal symptoms, and numbness of fingers and toes. A dose-response relationship was seen for leukopenia, thrombocytopenia, and the elevation of serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT). A Phase II study was then conducted in 641 patients to evaluate the efficacy of interferon alfa-2a in a number of disseminated malignant neoplasms. The 415 male and 226 female patients, almost all of whom had malignancies refractory to standard therapy, were treated with interferon alfa-2a at an initial daily dose of 3 X 10(6) U for 3 days. Doses were increased gradually at 3- to 7-day intervals until the therapeutic dosage was established. The daily dose could not exceed 50 X 10(6) U, and treatment was continued for at least one month. Efficacy rates, for 65 patients who achieved partial or complete responses, based on the total number of evaluable patients by cancer type were: 11/49 (22.4%), multiple myeloma; 4/21 (19%), lymphomas; 15/108 (13.8%), renal cell carcinoma; 2/30 (6.6%), bladder cancer; 4/39 (10.2%), brain tumors; 5/26 (19.2%), melanoma; 12/12 (100%), cutaneous lymphoma; 10/19 (52.6%), other skin cancers; 2/30 (6.6%), bone and soft tissue sarcomas. Overall, 65/371 (17.5%) of evaluable subjects responded.

A 60-year old woman with metastatic malignant melanoma who was well responded to a combination chemotherapy including DTIC was reported. She was noted a lentigo in the left first toe and histological examination revealed malignant melanoma in October 1978. Amputation of the left lower leg and dissection of the left inguinal lymph nodes had been done. OK-432 was injected as postoperative immunotherapy. She was readmitted to our hospital with the symptoms of pain and numbness of the left arm. Physical examination revealed a palpable mass in the left supraclavicular region. Incisional biopsy of the supraclavicular mass revealed metastatic malignant melanoma. She received a combination of 100mg DTIC i.v. for 5 days, 100 mg ACNU i.v. for one day and 1 mg VCR i.v. for one day (DAV chemotherapy) postoperatively. Subcutaneous injection of OK-432 with the dose of 5 KE per week was continued. Major side effects of DAV chemotherapy were nausea and transient leukocytopenia. No serious side effects were observed. On completion of the first course of DAV chemotherapy, abnormal shadow of the left apex was completely disappeared and on completion of the third course of DAV chemotherapy, high density area was markedly decreased in the cervical CT. She gained symptomatic reliefs and was discharged in August 1983. The combination chemotherapy including DTIC appeared to be effective in the treatment of metastatic malignant melanoma.

Taxol (paclitaxel, Bristol-Myers Squibb Company, Princeton, NJ), a drug extracted from the stem bark of the western yew, shows great promise as an antineoplastic agent for ovarian, breast, nonsmall cell lung, and head and neck cancers; melanoma; and leukemia. Although Taxol first was isolated in 1971, completion of many phase I studies was delayed until 1988, primarily because the drug caused severe hypersensitivity reactions. Other side effects of Taxol include cardiotoxicity, nausea and vomiting, diarrhea, mucositis, myelosuppression, tingling and numbness of the hands and feet, myalgia and arthralgia, alopecia, fatigue, headache, irritation at the injection site, and taste changes. Nursing care includes measures for preventing or minimizing side effects, close assessment and monitoring of potential side effects, patient education, and support. Because of the environmental impact of harvesting the western yew for Taxol, semisynthetic preparations such as taxotere are being explored.

A case of metastatic desmoplastic malignant melanoma is reported. The patient presented initially with a lung mass and subsequently developed facial swelling and numbness secondary to tumor involvement of the maxillary division of the trigeminal nerve. The pleomorphism, histochemistry, and schwannoid differentiation of these tumors is discussed.

A 64-year-old man presented with a pigmented cutaneous lesion on the right side of his face along with right facial numbness. Histological examination revealed malignant melanoma. Magnetic resonance imaging (MRI) revealed perineural extension along the entire course of the maxillary division of the right trigeminal nerve. This is a rare but important manifestation of the spread of head and neck malignancy.

Epithelioid malignant peripheral nerve sheath tumors are rarely found in cranial nerves. This report describes one such tumor originating from the infraorbital nerve in a 55-year-old man who presented with diplopia and right cheek numbness. Imaging showed a mass along the floor of the right orbit, which was excised. Histology suggested melanoma or carcinoma. Immunohistochemical staining was positive for S-100 and negative for HMB-45 and cytokeratin. Four other cases from the literature involving cranial nerves are discussed.

Meningeal melanocytoma is a benign lesion arising from leptomeningeal melanocytes that at times can mimic its malignant counterpart, melanoma. Lesions of the spine usually occur in extramedullary locations and present with spinal cord compression symptoms. Because most reported spinal cases occur in the thoracic region, these symptoms usually include lower extremity weakness or numbness. The authors present a case of primary intramedullary spinal meningeal melanocytoma presenting with bilateral lower extremity symptoms in which the patient had no known supratentorial primary lesions. Gross total surgical resection allowed for full recovery, but early recurrence of tumor was detected on close follow-up monitoring, allowing for elective local radiation without loss of neurological function. Case reports of such tumors discuss different treatment strategies, but just as important is the close follow-up monitoring in these patients even after gross total surgical resection, since these tumors can recur.
