Resumo: | Cutaneous tuberculosis is an uncommon disease, accounting for 1.5% of all types of tuberculosis. In pulmonary and cutaneous disease, infections caused by Mycobacterium africanum and Mycobacterium tuberculosis can be clinically indistinguishable. A six-year-old boy from Guinea-Bissau was hospitalized due to a right pre-auricular ulcer with two-year evolution and regional lymphadenopathy. Tuberculinic test was positive and the thoracic radiography showed a hypotransparent node on the right lower pulmonary lobe, with solid characteristics in CT scan. Skin ulcer and lymphadenopathy biopsies revealed lymphocytic infiltrate with a granulomatous reaction; the culture and PCR confirmed Mycobacterium africanum infection. Antibacillary treatment was supplied for six months, leading to significant reduction of the lesion. In developed countries it’s important to remind the several forms of cutaneous tuberculosis, which can present solely or in association with other forms of infection. In patients from endemic areas, a positive tuberculinic test should rise the suspicion of this entity. KEY-WORDS – Tuberculosis, cutaneous; Tuberculosis, pulmonary; Mycobacterium infections; Child. |

A tuberculose cutânea é uma doença incomum, constituindo 1,5% de todas as formas de tuberculose. Na doença pulmonar e cutânea, as infeções causadas por Mycobacterium africanum e Mycobacterium tuberculosis podem ser clinicamente indistinguíveis. Um rapaz de 6 anos da Guiné-Bissau foi hospitalizado devido a uma úlcera pré-auricular direita com evolução de dois anos e linfadenopatia regional. O teste tuberculínico foi positivo e a radiografia de tórax revelou um nódulo hipotransparente no lobo pulmonar direito, com características sólidas na TAC. As biópsias da úlcera e da linfadenopatia revelaram infiltrado linfocítico com reação granulomatosa; o exame cultural e a PCR confirmaram infeção por Mycobacterium africanum. Foi realizado tratamento antibacilar durante 6 meses, com redução significativa da lesão. Nos países desenvolvidos é importante relembrar as várias formas de tuberculose cutânea, que se pode apresentar isoladamente ou em associação com outras formas de infeção. Nos doentes provenientes de áreas endémicas, um teste tuberculínico positivo deve levantar a suspeita desta entidade.
