Introduction:Scrofuloderma is caused by Mycobacterium tuberculosis and is the most common form of cutaneous tuberculosis.It remains a significant medical challenge because it8 clinical manifestations mimic those of various other conditions,making diagnosis difficult.Here,we report a 28-year-old man who had been diagnosed with intestinal tuberculosis but discontinued treatment.Case presentation:He subsequently presented with a 5-month history of multiple non-healing ulcerative lesions on the abdomen with no other significant clinical findings.Ziehl-Neelsen staining of an impression smear taken from the lesions was performed as the preliminary investigation and confirmed the presence of acid-fast bacilli.Histopathologic examination of a skin biopsy specimen,PCR,and the Mantoux test also confirmed the presence of Mycobacterium tuberculosis.The patient began treatment with anti-tubercular drugs and his lesions gradually regressed.Discussion:The most common finding of scrofuloderma is a chronic,painless ulcerative lesion with purulent discharge.Cervical lymph nodes are frequently involved.These clinical features mimic several other bacterial and fungal conditions.However,Ziehl-Neelsen staining of the discharging ulcers can be used as a preliminary test to demonstrate acid fast bacilli in most of the cases.Histopathologic examination of skin biopsy specimen,culture on Lowenstein-Jensen media and PCR can confirm the diagnosis.Conclusion:Although Scrofuloderma is a rare cutaneous manifestation,it is curable with early diagnosis and prompt intervention of antitubercular drugs.
