Kaposi's sarcoma: a clinico-pathologic overview.

A careful overview of the classical appearances of Kaposi's sarcoma (KS) as well as of its variants were reviewed from the clinical and pathological point of view. The growth phases (stages) and the cellular patterns were histopathologically compared with emphasis on the developmental progression of disease as well as mitotic activity. Other morphological aspects were also assessed such as the features of the early phases and the incidence of hyaline bodies. One hundred and forty-three lesions from 96 patients mostly of the Italian sporadic type were investigated. A complete list of those entities which should be considered in differential diagnosis is shown and the dilemma of whether KS is a neoplasia or a hyperplasia is discussed.

[A case of Fiessinger-Leroy-Reiter syndrome. Etiopathogenic, diagnostic and therapeutic problems].

The Authors report the case of a young man with urethritis, conjunctivitis and oligoarticular arthritis. These symptoms are characteristic of Reiter's syndrome. Our patient also presented an inversion of CD4/CD8 ratio but the number and the activity of natural killer cells were normal and the research for HIV was negative. On the contrary the research for Chlamydiae by fluorescein-binding antibodies in urethral fluid was positive while the human leukocyte antigen HLA B27 was absent. The patient has been successfully treated by tetracycline and steroids. The Authors discuss the diagnostic, etiopathogenetic and therapeutical problems of this case, matching their findings to the up-to-date knowledge of Reiter's syndrome.

Cellular blue nevus of the scalp infiltrating the underlying bone: case report and review.

Cellular blue nevi (CBN) are benign tumors of the skin derived from dermal melanocytes histologically characterized by increased cellularity and often by a dual cell population of nevoid cells. CBN rarely tend to invade the underlying tissues. Only six cases of CBN of the scalp invading the skull have been reported. A new case of a CBN infiltrating the underlying bone is presented. The patient, a 23-year-old woman, had a large hairless area on her right parietal scalp, present since the early months of life. Her past medical history included, on the same site, the presence, at birth, of a raised, dark, soft and hairless mass that was subsequently electrodesiccated. Radiographs of the skull showed an area of osteolysis underlying the cutaneous lesion. Histologic examination of a biopsy specimen revealed a CBN of the scalp infiltrating the underlying bone. Surgical resection of the entire lesion was planned. There were no other anomalies or malignancies. The patient is currently being followed in our clinic.

Inflammatory cutaneous metastasis from laryngeal carcinoma.

The authors report the case of a 64-year-old man who presented with erythematous infiltrating plaques sited on his right supraclavicular and infraclavicular regions. Five years before a laryngeal epidermoid carcinoma had been surgically removed. After two years the patient underwent lymphadenectomy and radiotherapy for the presence of metastasis in his right cervical lymph nodes. He was disease free until two months before our examination when small red spots appeared on his right supraclavicular region, slightly enlarging. A skin biopsy was performed and histological examination showed the presence of metastatic cells inside dilated lymphatic vessels. Immunohistochemical markers showed only positive staining of atypical cells with monoclonal anti-cytokeratin antibodies (cytokeratin B-ORTHO=34betaE12) confirming the epithelial origin of metastastic cells. A diagnosis of inflammatory cutaneous metastasis from laryngeal epidermoid carcinoma was given. This type of metastasis has been frequently observed in patients with breast carcinoma and it has also been described during the course of other malignant tumours. Malignant tumour of the larynx generally spreads to regional lymph nodes or, through blood, to the lungs. Skin metastasis have rarely been described, and always as multiple or solitary nodules. According to our knowledge this is the first case of inflammatory cutaneous metastasis from laryngeal epidermoid carcinoma reported in the literature.

Genital porokeratosis.

We report on a negroid male suffering from porokeratosis of the scrotum. Porokeratosis in the genital area is rare, as is its occurrence in negroid people. In our patient, we found an asymptomatic non-HIV associated immunosuppression. In this case, the disease might be called porokeratosis of Mibelli. The diagnosis should be suspected in patients not belonging to one of the classical at-risk ethnical groups if the skin lesions seem typical.

[Anorectal neuroendocrine carcinoma: observations on a case and review of the literature].

Carcinoid tumours of the anorectum are rare (0.7% of malignant rectal tumours). Because of this rarity several aspects of the management of these tumours remain controversial. Diagnosis may be delayed because of failure to recognize their morphological characteristics and histological appearance may not reflect their biological behaviour. Immunocytochemistry for neuroendocrine-cells are essential to identify different types of carcinoid tumours and to do differential diagnosis from other malignant tumours. All that allow an exact therapeutic approach to these tumours. The tumours less than cm 1 in diameter can be safely treated by local excision; the tumours more than cm 1 in diameter are treated by radical surgery (AAP).
