Verrucous carcinomas are lesions occurring mainly in the buccal mucosa but sometimes they arise also in the larynx. The disease is characterized by a cornifying verrucous proliferation of the squamous epithelium, without atypias or
metastases
. The clinical and histological pictures of six observations are described and the differential diagnosis from hyperkeratotic papillomas and benign
keratosis
of the larynx are discussed. In one of these cases, 13 years after the beginning of the disease a focal cancerisation could be observed. The authors consider this disease not as a carcinoma and are not sure whether it is a true tumor at all. They propose therefore the name "verrucous acanthosis" instead of verrucous carcinoma and classify these lesions as facultative precanceroses.

In 21 patients with a variety of skin tumors (squamous cell carcinomas, malignant melanomas, basal cell epitheliomas and mycosis fungoides) or pre-cancerous lesions (Bowen's disease,
actinic keratosis
, junctional nevus cell nevus) the radioactive phosphorus uptake test demonstrates a significantly increased concentration of P32 in those tumors. There were no false negative tests. The possibility of differentiation of malignant melanoma from benign nevus cell nevus and the early recognition of cutaneous
metastases
is described. Furthermore recurrence of previously irradiated or excised basal cell epitheliomas can be detected without a biopsy. No hematological side-effects were observed.

In the period from 1980-1989, 199 laryngomicroscopical examinations were conducted at our department. There were 20 cases of laryngeal carcinoma, 55 cases of
keratosis
with the presence of dysplasia in 21.8%, as well as 19 papillomas in adult individuals. In our material keratoses appear a few years before the onset of laryngeal carcinoma in an average statistical distribution. With one exception, the carcinomas were detected before the appearance of
metastases
. Our data indicate the exceptional benefit of laryngomicroscopy in the detection of precancerous lesions and carcinoma of the larynx.

Between 1976 and 1988, 135 patients with
solar keratosis
(SK) and 53 patients with squamous cell carcinoma (SCC) on the sun-exposed skin, but without apparent preceding diseases such as burn scars, chronic radiodermatitis, chronic arsenic poisoning, or xeroderma pigmentosum, were encountered. Sixteen of the SCC patients also had SK on other areas of sun-exposed skin. There were 31 SCC patients also showing SK (SK-SCC) and 22 SCC not showing SK (DN-SCC) within the same histologic sections. The mean ages of the patients with SK-SCC and with DN-SCC were similar.
Metastases
to regional lymph nodes were observed in 5 SK-SCC patients, of whom 3 died of the disease, and in 5 DN-SCC patients, of whom 4 died of the disease. The five-year post-operative survival rates were 70% in SK-SCC and 74% in DN-SCC; the ten-year post-operative survival rates were 70% in SK-SCC and 44% in DN-SCC.

Actinic squamous-cell carcinoma has been described to have a low risk of metastasis. Reported here are four Japanese cases of lymphatic metastasis of squamous-cell carcinoma derived form
solar keratosis
. The primary lesions were on the face in three cases and on the back of the hand in one. Two patients died, and others had recurrent incurable metastatic lymph nodes. Therefore, it is noteworthy that actinic squamous-cell carcinoma in the Japanese can become so aggressive and
metastasize
.

The distribution of type IV collagen in benign and malignant epithelial proliferations of the breasts, the lungs, and the skin was studied by an indirect immunofluorescence technique using specific antiserum. In benign lesions of the breasts, the staining for type IV collagen was present in all vascular and glandular basement membranes. In basal cell carcinoma of the skin, the basement membrane labeling was also found to be continuous. In malignant lesions of the breasts, the lungs, and the skin, staining for type IV collagen was seen only around well-differentiated glandular structures and in close contact to basal epidermal cells. This staining appeared as an irregular network. Of particular interest was the localization of type IV collagen in non-infiltrating lesions of the breasts and the bronchi where discontinuity in the basement membrane staining was observed. In contrast, there were no disruptions of basement membrane labeling in skin
senile keratosis
and in Bowen's disease. We conclude that the loss of type IV collagen seen in malignant proliferations in our study is related to overt or potential tumor cell infiltration and aggressiveness.

We report on an 84-year-old female patient who presented with abundant firm skin nodules and massive lymphoedema restricted to the left leg. Metastasizing eccrine porocarcinoma was diagnosed by the unusual circumscribed pattern of the cutaneous
metastases
and the histological detection of intraepidermal and intradermal PAS-positive tumour cells. This diagnosis was established by the histopathological reexamination of a small skin tumour on the left ankle, which had been misinterpreted as
actinic keratosis
5 years before. The initiated local radiation therapy with fast neurons and cobalt-60 resulted in partial regression of the cutaneous
metastases
and lymphoedema, but was not able to hamper the fatal outcome directly resulting from tumour cachexia.

The clinical findings, histopathology, management and outcome of 31 patients with verrucous squamous cell carcinoma of the larynx (VSCC) are discussed. Laryngeal VSCC is a rare, highly differentiated variant of SCC and has specific morphological features and clinical behavior. A close liaison between the laryngologist and pathologist is needed to formulate a correct diagnosis, because this tumor appears to be malignant clinically and histologically benign. A low-power magnification of multiple large specimens, including the deep margins of the lesion, is required in order to differentiate VSCC from
keratosis
, verruca vulgaris or SCC with verrucous appearance, and to detect underlying microscopic foci of invasive SCC within or adjacent to a verrucous carcinoma. Long-lasting hoarseness was the most common symptom as the glottic region was the most common site of VSCC. Presumed clinically positive N1 lymph nodes were observed in the necks of 7 patients, but none had
metastatic disease
on histopathological study. Surgery alone was the most effective form of treatment, as it allowed a good outcome of all treated patients. Surgery plus radiotherapy was associated with an early recurrence and a poor outcome in 2 of 7 patients treated. The generally "benign" behavior of VSCC allows for conservative surgery, with complete endoscopic resection using the carbon dioxide laser representing a more conservative surgical approach. Neck dissection is not indicated due to the non-metastatic behavior of this tumor.

Basal cell and squamous cell carcinomas are the most common skin cancers, occurring mainly on sun-damaged skin of old persons. Basal cell carcinoma is a neoplasm of follicular germinative cells which may infiltrate and destroy adjacent tissues, but rarely metastasizes. Five clinico-pathologic types of basal cell carcinomas can be recognized, namely, nodulo-ulcerative, superficial, morpheiform, fibroepithelial, and infundibulo-cystic.
Actinic keratosis
and Bowen's disease are intrepidermal proliferation of atypical keratinocytes that eventually may progress to become over squamous cell carcinoma. Lesions arising in sites of chronic injury or scarring bear an higher risk of
metastases
. Keratoacanthoma is a rapidly evolving tumor of keratinocytes that resolves spontaneously. Keratoacanthoma might represent a self-healing type of squamous cell carcinoma.

Actinic keratoses (AKs) are primarily induced by ultraviolet (UV) radiation and are often identified as premalignant lesions. In our opinion, AKs are proliferations of transformed, neoplastic keratinocytes confined to the epidermis that may eventually extend into the dermis, at which point they are termed squamous cell carcinoma (SCC). In contrast to AKs, SCCs have the potential to
metastasize
and kill. This process is analogous to that of evolving carcinoma of the uterine cervix that has been termed cervical intraepithelial neoplasia (CIN), a time-tested and reliable classification that provides clinicians with accurate information on which to base treatment decisions regarding cervical neoplasms following biopsy testing. A similar classification scheme could provide guidance to clinicians for the diagnosis and treatment of evolving SCC of the skin and as such, we propose a similar classification using the terminology keratinocytic intraepidermal neoplasia (KIN). This system is more reflective of the histology and natural history of SCC and eliminates ambiguity in the terminology of lesions currently referred to as AKs. The KIN classification defines features by which individual specimens can be objectively graded and specific treatment recommendations are made based on the grade of the lesion. We propose that the term keratinocytic intraepidermal neoplasia (KIN) be used to define and describe evolving SCC of the skin and that the term actinic (solar)
keratosis
be eliminated.
