Sir,
A 32-year-old man presented with multiple, asymptomatic, erythematous papules on the face for 6 months. The lesions gradually increased in size and number to involve the neck and both forearms over the last 2 months. There were no systemic symptoms. Examination showed multiple, discrete, non-tender, symmetrical, reddish-brown papules on the forehead, both cheeks, neck and eyelids [Figure - 1]. Erythematous papules and nodules were also present on the dorsum of the hands and extensor aspect of the forearms [Figure - 2]. There was no regional lymphadenopathy. Blood investigations such as complete blood count, erythrocyte sedimentation rate and hepatic and renal function tests were normal. Chest X-ray was normal and Mantoux test was negative.

Biopsy was taken from a facial lesion as well as a lesion on the forearm. Histopathology of lesion from face showed central areas of caseation necrosis in the dermis with surrounding tuberculoid granulomatous infiltrate consisting of histiocytes, epithelioid cells, giant cells and lymphocytes [Figure - 3] and [Figure - 4]. Biopsy from the papule on the forearm showed similar histological features as seen in facial lesion [Figure - 5] and [Figure - 6]. Special stains for tubercle bacilli were negative. The patient was treated with doxycycline leading to resolution of the lesions leaving behind pitted scars over a period of 3 months of treatment [Figure - 7] and [Figure - 8].

Lupus miliaris disseminatus faciei is an uncommon, chronic, inflammatory dermatosis characterized by multiple, monomorphic, symmetrical, reddish-brown papules on chin, forehead, cheeks and eye lids. The lesions usually regress spontaneously within months to some years leaving behind depressed scars.
Histopathologically, it is characterized by a dermal granulomatous infiltrate with a central area of caseation necrosis. Histopathological findings range from perivascular and periadnexal lymphohistiocytic infiltrate in early lesions and epithelioid cell granuloma with or without central necrosis in well-developed lesions. Late lesions show extensive perifollicular fibrosis with non-specific cell infiltration.
The exact etiopathogenesis of this condition is unclear. Earlier it was thought to be a “tuberculid,” but it is no longer thought to be of tuberculous origin. It is hypothesized that the condition is due to immune response to the follicular antigens that are released due to damage to the hair epithelium, triggering an autoimmune reaction directed against hair-follicles. Other authors consider it to be a variant of granulomatous rosacea due to the centrofacial distribution and granulomatous histopathology. However, some believe that it is an entity distinct from either skin tuberculosis or granulomatous-type rosacea and propose to change its name to “facial idiopathic granulomas with regressive evolution.”[1]
Various treatments have been advocated and these include tetracycline, prednisolone and isotretinoin. Isoniazid and dapsone have also been reported to be useful.[2]
Face is a common site for lupus miliaris disseminatus faciei lesions and extrafacial involvement is rarely seen, with only a few reports of the latter. Extrafacial sites reported include axillae, neck, scalp, legs, trunk and genitalia. Kou et al. have described extrafacial distribution of lesions without face involvement.[3]
Nath et al. have reported the extensive involvement of the face with unusual linvolvement of the ear lobes, neck and the shoulder girdle in an Indian patient.[4] A case of extrafacial lupus miliaris disseminatus faciei alongwith Morbihan disease and with axillary acneagminata has been reported.[3] However, in our patient, these associations were not seen. Bedlow has described a case of two adults with involving axillae with no facial lesions.[5]
We report this case to emphasize the relatively rare extrafacial distribution of lupus miliaris disseminatus faciei involving the dorsae of hands and forearms.
