We describe a rare case of a subcutaneous infection by both Phaeoacremonium venezuelense and Plectophomella sp. in a Brazilian male. Sequencing of a beta-tubulin gene fragment allowed us to confirm the identification of the former. However, a similar procedure of sequencing rRNA gene fragments was not useful for the identification of the latter fungus.
Marjolin’s ulcer was first described in 1828 and involves a rare, malignant transformation of chronic scar tissue or ulcers. The delay between the occurrence of the scar and malignant transformation can be as long as 70 years. Although rare, this association between chronic ulcers and squamous cell carcinoma (SCC) is well documented, although the clinical… (More)
CONTEXT Sentinel node (SN) biopsy has changed the surgical treatment of malignant melanoma. The literature has emphasized the importance of gamma probe detection (GPD) of the SN. OBJECTIVE Our objective was to evaluate the efficacy of patent blue dye (PBD) and GPD for SN biopsy in different lymphatic basins. DESIGN Patients with cutaneous malignant… (More)
We report a case of a 55-year-old man who, after a 6-month history of enlargement of cervical lymph nodes, presented with multiple painful ulcerations of the oral mucosa and lips and multiple skin erosions on the trunk, back, extremities, and genitals. A lymph node biopsy was performed and revealed diffuse peripheral B-cell non-Hodgkin lymphoma. Skin biopsy… (More)
The authors report a case of lepromatous leprosy associated with dermatopolymyositis and gastric adenocarcinoma. The literature is reviewed and the authors discuss about this association.
To evaluate the involvement of the heart in patients with seronegative spondyloarthropathies by echodopplercardiography, 35 patients including 20 with ankylosing spondylitis, 10 with Reiter's syndrome and 5 with psoriatic arthritis (21 men and 14 women, with ages ranging from 17-68 years and averaging 38.5) were studied. Most were asymptomatic with respect… (More)
The authors present a study of hypersensitivity of patients with Hebra's prurigo (HP) to feleabites. Thirty six patients were studied. With the results obtained the following conclusions are held: 1. Among the probable responsible factors found in the history of patients with HP, the flea bite is the principal factor. 2. Almost all the patients with HP who… (More)
