We report a case of a 57 year-old male who developed atypical bullous disease and in whom an underlying carcinoma of the bronchus was found. The cutaneous eruption fulfilled the clinical, histological and immunological features of pemphigus herpetiformis. Reports of pemphigus herpetiformis and internal malignancy are extremely rare.

Because of its rarity and its fast development, we report a case of a 84-year-old woman, who developed all the clinical and histopathological characteristics of the angiosarcoma of face and scalp, with a fatal evolution within four months and metastases to liver, lungs and bone marrow.

We present a four year old boy with Björnstad syndrome. The hair showed typical features of pili torti which were confirmed by optical and scanning electron microscopic evaluation. On computerized X-ray diffraction the hairs showed no abnormal constituents. There was a serious bilateral sensorineural deafness.

This case report describes the simultaneous occurrence of antiphospholipid antibody syndrome in a patient with cutaneous T-cell lymphoma. An abnormal T cell-B cell cooperation is postulated to explain this unusual association. To the best of our knowledge, no similar cases have been reported previously.

Infantile myofibromatosis is included in fibrous proliferations of infancy, processes with specific clinic, histology, and evolution, that are characterized by nodules in the skin, bones, and viscera. It's prognosis is varied, depending on whether it is manifested in the solitary or multicentric form. We describe a patient with congenital solitary myofibromatosis.

This case report describes the simultaneous occurrence of pyoderma gangrenosum and subcorneal pustular dermatosis. They are both neutrophilic dermatoses that have been described associated in several instances. The association of pyoderma gangrenosum and other cutaneous diseases is also reviewed.

Lichen amyloidosus is a chronic pruritic skin disorder, unusual among Europeans, and classically seen over the shins. The exact nature of the amyloid fibril protein, in lichen amyloidosus, is a matter of controversy and no specific treatment is available. Diffuse cutaneous involvement in a 60-year-old portuguese man is described. New pathogenic aspects and recent therapeutic approaches are discussed.

The case of a patient with thoracic abdominal and left arm, migratory erythema-edematous plates over a space of three years is described. The histopathologic features reveal a eosinophilic panniculitis due to probable larva migrans (gnathostomiasis). This appears to be the first report on the subject because we have not found any reference to the subject in Argentina bibliographic search.

Patients with sarcoidosis that present only cutaneous lesions are uncommon but have been described. In countries where leprosy occurs as an endemic disease the differential diagnosis between sarcoidosis and tuberculoid leprosy may be difficult to establish. In order to entrance the correct diagnosis this study presents a table in which the results of lepromin and Kveim tests are analyzed are correlated to the other.

A 22-year-old female with two woolly hair nevus of the scalp and a systematized epidermal nevus is reported. This association has been rarely described. Scanning electron microscopy of the woolly hair demonstrates oval and triangular hair shaft sections and longitudinal grooves. The structure of the cuticle was not disturbed.
