[Ecology of a focus of cutaneous leishmaniasis in the Thies region (Senegal, West Africa). 2. Epidemiological and clinical peculiarities of the human disease].

During their epidemiological survey of a cutaneous leishmaniasis focus, the authors study the epidemiological and clinical aspects of 60 proven human cases observed in the studied area (Thies region). The disease can occur at any age but is more frequently seen in the pre-adolescent (10-15 years), adolescent (15-20 years) and adult (20-40 years) age classes. During the year, 76.5% of the lesions appear between july and the end of november. The spontaneous evolution of the disease seems to have a one year duration. Less than 10 lesions are observed in the majority of the cases (91.5%). The lesions are mainly located on upper and/or lower limbs and are generally of humid ulcerated type, often covered by a deep scar; a lymphatic nodular dissemination from a lesion occurs in 25% of the cases.

[Leprosy tests: diagnostic problems (apropos of 2 cases)].

Two cases of reactional leprosy leading to wrong diagnosis are reported. The first one concerns a reversal reaction predominantly neuritic, initially taken for polyarthritis. The second one concerns an erythema nodosum leprosum with extensive cutaneous necrosis (Lucio's phenomenon or ulcerative lazarine leprosy). Main aspects and mechanisms of leprosy reactional states are reviewed. It is emphasized that errors or delays in diagnosis are often caused by failing to recognize cutaneous or neuritic symptoms.

[Red grain mycetomas (A. pelletieri). Apropos of 20 new cases in Dakar].

20 cases of mycetoma A. pelletieri coming from Sénégal are reported. This series confirms the peculiar localisation, extension and severity of this type of mycetoma: 14 cases located outside the foot (buttock, perineum, scrotum, inguinocrural area, abdominal and chest wall); frequency of lymph node involvement; importance of superficial extension; surgical possibilities overreached in more than 1/3 of the cases. Effectiveness of sulfa-methoxy-trimethoprime in the medical management is outlined.
