Syncephalastrum species producing mycetoma-like lesions

Mycetoma

A 32-year-old woman from northeastern Brazil worked in farming and presented with a 6-year history of progressive swelling of the left foot. Swelling and sinuses draining purulent discharge with white grains ( Figure 1 ) were present. Potassium hydroxide preparation of drainage showed whiteyellowish nodules with fine filaments. Culture of the grains on Sabouraud agar and the casein hydrolysis t...

Mycetoma

Mycetoma is a chronic infective condition of tropical and subtropical regions. It is commoner in males, especially those in their third or fourth decade who work on the land. The clinical triad of subcutaneous nodule, sinuses and discharge usually leads to diagnosis; the disease is commonly painless. Treatment is by extensive surgical excision of affected areas and may include limb amputation. ...

New species of Madurella, causative agents of black-grain mycetoma.

A new species of nonsporulating fungus, isolated in a case of black-grain mycetoma in Sudan, is described as Madurella fahalii. The species is characterized by phenotypic and molecular criteria. Multigene phylogenies based on the ribosomal DNA (rDNA) internal transcribed spacer (ITS), the partial β-tubulin gene (BT2), and the RNA polymerase II subunit 2 gene (RPB2) indicate that M. fahalii is c...
