Plantar lichen planus masquerading eumycetoma of dark grains

Lichen planus is a common inflammatory disease but its perforating variety is not so common and it has been described in small number of text and articles. Here we reported a case of plantar lichen planus where there was a history of discharge of dark grains from the sole of foot and diagnosing the disease as eumycetoma of dark grains repeated antifungal therapy could not resolve the lesions and histopathologically it showed the classical pictures of lichen planus. Collaborating the clinical and histological features we have diagnosed the case as perforating lichen planus but Verhoeff-Van Gieson stain could not elucidate the perforating channel which ot difficult to delineate and often missed. So, we have put the diagnosis of plantar lichen planus and treated with intramuscular triamcinolone and the lesions resolved.

马杜拉分支菌引起下颌部真菌性足菌肿一例

目的探讨1例真菌性足菌肿的临床病理特点、诊断、治疗及预后,并对其致病菌进行鉴定。方法分析我科收治的1例下颌部真菌性足菌肿的临床及病理特点,进行真菌学及分子生物学鉴定。结果该患者以下颌部肿胀、多发窦道形成、排大量黑色颗粒为主要症状,病理检查示化脓性肉芽肿性炎症,PAS染色可见大量藕节状真菌菌丝。ITS1、ITS2和D1/D2区测序结果示:病原菌与足菌肿马杜拉分支菌有最大的相似性,但相似性小于97%。结论本病例为发生在下颌部的由马杜拉分支菌属内一新的菌种引起的真菌性足菌肿。
