Proximal-type epithelioid sarcoma -- case report.

Epithelioid sarcoma, first described by Enzinger in 1970, is a rare soft-tissue sarcoma typically presenting as a subcutaneous or deep dermal mass in distal portions of the extremities of adolescents and young adults. In 1997, Guillou et al. described a different type of epithelioid sarcoma, called proximal-type epithelioid sarcoma, which is found mostly in the pelvic and perineal regions and genital tracts of young to middle-aged adults.

Lobomycosis and squamous cell carcinoma.

The occurence of squamous cell carcinoma on long-lasting ulcers is classic. Malignant transformation may occur on burn scars and chronic ulcers of varying etiology, including infectious agents. Transformation of old lobomycosis lesion scars into squamous cell carcinoma has been rarely reported.

Kindler syndrome: report of two cases.

Kindler syndrome is a rare autosomal recessive genodermatosis characterized by trauma-induced blisters, progressive poikiloderma and varying degrees of photosensitivity. In 2003, loss-of-function mutations were identified in the gene KIND1 mapped to chromosome 20p12.3.

Histoplasmosis and AIDS co-infection.

This report concerns an AIDS patient presenting systemic and cutaneous manifestations of histoplasmosis. A histopathological and mycological examination of the skin lesion confirmed the diagnosis. In AIDS patients histoplasmosis arises mainly when the T-CD4+ cell count is less than 50 cells/mm3.

AIDS-associated paracoccidioidomycosis in a patient with a CD4+ T-cell count of 4 cells/mm³.

We describe a case of a patient presenting with HIV and paracoccidioidomycosis co-infection. At the time of diagnosis total CD4+ T-cell count was 4 cells/mm3. Histopathology revealed tuberculoid granulomas, scarce CD4+ T cells, a moderate number of CD8+ cells and the absence of Foxp3+ cells.

Do you know this syndrome?

Barraquer-Simons syndrome, also called acquired partial lipodystrophy or cephalothoracic lipodystrophy, is a rare form of progressive lipodystrophy, characterized by symmetrical lipoatrophy of subcutaneous adipose tissue starting in the head and spreading to the thorax, upper and lower limbs and thighs. In this work, we report the case of a patient with Barraquer-Simons syndrome without systemic complications.

Borderline lepromatous leprosy.

It is presented a case of borderline lepromatous leprosy with 4 years of evolution and cutaneous lesions of difficult diagnosis in the National Health System. The histopathological evaluation, which was essential for the diagnosis, showed disorganized granulomatous structures and multiple alcohol -acid resistant bacilli. Cases like the one described here are responsible for the contamination of cohabitants and the appearance of new cases of leprosy.

Leprosy and HIV coinfection: a clinical, pathological, immunological, and therapeutic study of a cohort from a Brazilian referral center for infectious diseases.

Background: Although awareness of the relevance of leprosy and human immunodeficiency virus (HIV) coinfection is increasing worldwide, several aspects of this co-occurrence are not fully understood.

Methods: We describe clinical, pathological, immunological, and therapeutic long-term follow-up of a cohort of 25 individuals with leprosy and HIV infection from Manaus, Amazonas.

Results: Careful description of our cohort indicates a higher prevalence of leprosy in an HIV-positive population than that in the general population.

Lobomycosis.

A case of lobomycosis in a patient from the Brazilian Amazon region is presented. Lobomycosis is a subcutaneous mycosis caused by the yeast Lacazia loboi. It often affects adult males and has been reported in dolphins.
