RESUMO
Microsporum canis is one of the zoophiles and pets(especially dogs and cats) play a role as a source of this organism. M. canis is most likely transmitted by contact of these animal hosts with humans. We report on 16 foreigners who are infected with M. canis transmitted from a show tiger. Fourteen of the patients had directly contact with a show tiger on occasion. Patients showed typical tinea corporis lesions on the extremities, and the tiger showed hairless patches on the abdomen. The culture and microscopic findings from patients' lesions revealed M. canis as the causative fungus.

Epithelioid hemangioendothelioma(EH) is a low-grade tumor of vascular endothelial cell origin, which most commonly occur in the lower extremities of middle-aged patients with an equal gender distribution. It may occur on internal organs such as the liver or lung or bones. A 54-year-old woman who had a history of metastatic adenocarcinoma of unknown origin on the right inguinal lymph node, was presented to us because of a 1.0 x 1.0cm-sized and 2 x 2cm-sized two subcutaneous nodule on her right shin. On H & E stain, there were nests of round nucleated, polygonal, vacuolated cells, some of which contained fragmented erythrocytes. Factor VIII related antigen, CD31 was positive. A diagnosis of epithelioid hemangioendothelioma was established based on histologic, immunohistochemical studies. Wide excision was performed. There was no recurrence nor the development of new lesions so far.

Confluent and reticulated papillomatosis(CRP) is a rare dermatosis. The lesions are hyperkeratotic, verrucous papules and plaques, resulting in a confluence of lesions centrally and a reticulated pattern at the periphery. It is more common in women and during puberty. The histopathological findings show papillomatosis, hyperkeratosis and a sparse superficial perivascular lymphocytic infiltrate. We report a case of CRP that responded to oral etretinate in an 18-year-old man.
