Lupus Miliaris Disseminatus Faciei: A Report of a Rare Case and Its Differential Diagnosis

Abstract

Lupus miliaris disseminatus faciei (LMDF), often known as "acne agminata," is an uncommon illness that causes facial papules. Clinically, it has monomorphic reddish-brown, dome-shaped central papules with periorbital location. Histopathologically, a cutaneous granulomatous response is common around hair follicles and is accompanied by central necrosis. In the dermatology outpatient clinic, a 51-year-old woman had many tiny papules on her right side malar area for one to two months. Few of them started to regress and demonstrated healing with superficial scarring. The pathology showed a granulomatous response on microscopy, and histology and clinical correlation confirmed the case as Lupus miliaris disseminatus faciei. LMDF must be distinguished from tuberculous granuloma, granulomatous rosacea, and perioral dermatitis. The patient was prescribed systemic dapsone and topical tacrolimus therapy, and the lesion improved at the follow-up visit.
