Tuberculous origin should be considered in persistent perianal ulcers to avoid delays in the treatment of this rare form of tuberculosis.

Microsporum species are a frequent cause of cutaneous mycoses in humans. Atypical strains of Microsporum can sometimes be difficult to identify with conventional methods. Recently, we have obtained a Microsporum isolate with atypical morphology and special nutritional requirements (Microsporum CHUS-126-02). As several molecular techniques have been developed for the identification of fungi, we analysed six Microsporum species (M. canis, M. gypseum, M. gallinae, M. nanum, M. ferrugineum and M. persicolor) in order to compare them with our isolate, by using polymerase chain reaction-restriction enzyme analysis (PCR-REA). We studied the nucleotide sequence of the internal transcribed spacer regions from the nuclear DNA encoding for the ribosomal domain. Digestion with MvaI and EcoRI endonucleases obtained specific patterns for M. gypseum, M. gallinae, M. nanum and M. persicolor. Microsporum canis, M. ferrugineum and Microsporum CHUS-126-02 yielded the same patterns. Based on these results and phenotypic criteria, we classified our atypical isolate as M. canis.

Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare inherited condition that includes characteristic eyelid malformations and sometimes reduced fertility in females. Genetic studies have implicated mutations in the forkhead transcription factor FOXL2 as responsible for BPES. We report a female and her father with BPES type I, who presented the 1092-1108dup17 mutation in the FOXL2 gene. Molecular studies and the typical clinical features of BPES should allow the dermatologist to reach an early diagnosis and permit the treatment of eyelid alterations and the investigation of infertility.
