Our study aimed to describe the epidemiological, clinical, and diagnostic aspects of African histoplasmosis in Togo through a descriptive and cross-sectional study on histological diagnosed African histoplasmosis in Pathology Department of Lomé from 2002 to 2016 (15 years). A total of 17 cases of African histoplasmosis were diagnosed. The sex ratio (M/F) was 1.8. The annual incidence was 1.1 cases. The mean age of the patients was 27.2 ± 0.4 years. All our patients were of social categories with a low socioeconomic level. HIV infection was known in 3 patients and one patient contracted tuberculosis. The clinical manifestations were cutaneous in 7 cases, cutaneous and mucous in 3 cases, cutaneous and lymph node in 3 cases, cutaneous and bone in 2 cases, and disseminated in 2 cases. The samples examined consisted of 14 cutaneous biopsies measuring 2-3 cm and 3 ganglionic biopsies each measuring 4 cm of major axis. Histologically, all cases were of chronic form made of granulomatous reaction with ovoid yeasts measuring between 1 and 2 microns. Despite the low frequency of this disease in our country, it should be kept constantly in mind before any granulomatous lesions, especially in the context of the HIV pandemic.
我们的研究旨在通过对2002年至2016年(15年)洛美病理科经组织学诊断的非洲组织胞浆菌病进行描述性横断面研究,来阐述多哥非洲组织胞浆菌病的流行病学、临床和诊断方面的情况。共诊断出17例非洲组织胞浆菌病病例。男女比例(男/女)为1.8。年发病率为1.1例。患者的平均年龄为27.2±0.4岁。我们所有的患者都属于社会经济水平较低的社会阶层。3例患者已知感染艾滋病毒,1例患者感染了结核病。临床表现为皮肤型7例,皮肤黏膜型3例,皮肤淋巴结型3例,皮肤骨型2例,播散型2例。所检查的样本包括14份2 - 3厘米的皮肤活检样本和3份每份长径为4厘米的淋巴结活检样本。组织学上,所有病例均为慢性型,由肉芽肿反应组成,伴有大小在1至2微米之间的卵圆形酵母。尽管我国这种疾病的发病率较低,但在出现任何肉芽肿性病变时,尤其是在艾滋病毒大流行的背景下,都应始终牢记该病。
