Granulomatous mycosis fungoides is a rare subtype of T-cell cutaneous lymphoma. Due to its clinical heterogenicity the diagnosis is delayed and based on histopathological and immuno-histochemical findings, sometimes requiring gene rearrangement studies for confirmation. We report the case of a patient who was submitted to several biopsies before diagnostic conclusion.

Granulomatous amoebic encephalitis caused by Balamuthia mandrillaris is an uncommon infection for which there is no optimal therapy. We describe a young, female patient who presented with extensive cutaneous and neurological involvement and who recovered after receiving prolonged treatment with miltefosine, fluconazole, and albendazole.

Granuloma annulare is one of the granulomatous dermatoses, the localized form of which is the most common clinical type, although rare variants such as subcutaneous form have been reported.We present a 22-year-old girl with asymptomatic cutaneous lesions on her fingers from 14 years ago.On physical examination, multiple nodules with rubbery consistenc...

We report a 62-year-old male who presented status post lung transplantation with subcutaneous nodules. One week later, he showed signs of altered mental status; brain imaging demonstrated mass effect in the cerebellum and meningoencephalitis. In spite of treatment with a broad range of antimicrobials, he died. A punch biopsy of the skin lesions showed a superficial and deep mixed inflammatory i...

Striking differences were observed between the visceral and cutaneous responses after tests with validated Kveim and normal spleen suspensions in a guinea pig model of granulomatous bowel disease. Five of six animals sensitised with BCG showed positive responses at the ileal Kveim test site whereas all six had negative cutaneous Kveim tests. Conversely, two of six animals sensitised with irradi...

A murine model of cutaneous leishmaniasis with green fluorescent protein positive (GFP+) L. major enables the monitoring of parasitic load via measurements of GFP fluorescence intensity, allowing for a faster and more efficient way of monitoring the clinical outcome of photodynamic therapy (PDT). This model may provide new insights on the phototoxic aspects in PDT. Although PDT regimens may be ...

This study reports two cases of chronic paracoccidioidomycosis with sarcoid-like cutaneous lesions. The patients began the treatment in 2013 at Hospital Universitário Clementino Fraga Filho (HUCFF) of the Universidade Federal do Rio de Janeiro (UFRJ). The first case (mild form) was treated with trimethoprim-sulfamethoxazole (8 mg /kg per day, orally) for three months and, then, with half the do...

Entecavir (Baraclude®, Bristol-Myers Squibb) is a potent and selective antiviral agent that has demonstrated efficacy in patients with chronic hepatitis B. The most frequent adverse events attributed to entecavir include increased alanine aminotransferase, upper respiratory tract infection, headache, abdominal pain, cough, pyrexia, fatigue, and diarrhea. Although quite a few randomized double-b...

B-cell chronic lymphocytic leukemia (B-CLL) is a low-grade lymphoproliferative disease. Cutaneous involvement of B-CLL is limited and, in most cases, it represents non-specific manifestations related to an impaired immune system. Leukemic skin infiltrates (leukemia cutis) occur in 4-20% of patients. Herein we report the case of a 65-year-old woman with B-CLL presenting with papular, nodular, an...

Cutaneous leishmaniasis is a protozoan infectious disease and widespread in Mediterranean basin including Turkey. Lesions usually start with erythematous papules, gradually enlarges and afterwards it ulcerates. We present a 12-year-old boy with diffuse persistent lip swelling mimicking granulomatous cheilitis. Systemic glucantime was started. However, severe hypotension and bradycardia was deve...
