Lupus Miliaris Disseminatus Faciei versus Granulomatous Rosacea: A Case Report

Lupus miliaris disseminatus faciei (LMDF) and granulomatous rosacea are 2 distinct inflammatory dermatoses with overlapping clinical features: reddish-yellow papular eruptions localized on the central face. Consequently, LMDF can easily be misdiagnosed as granulomatous rosacea or vice versa. Because delayed treatment in LMDF may increase chances of permanent scar formation, accurate diagnosis is important. We therefore analyzed published literature and case studies to organize the essential features differentiating LMDF from granulomatous rosacea. In addition, we report each case of LMDF and granulomatous rosacea for direct comparison.

Granulomatous Rosacea in Korean Patients: Diagnosis Based on Combining Clinical and Histological Findings

<b><i>Background:</i></b> Granulomatous rosacea (GR) is a rare inflammatory skin disease, which is considered a variant of rosacea, apart from other types of rosacea. <b><i>Objective:</i></b> This study aimed to summarize the characteristics of Korean patients diagnosed with GR by combining clinical and histological findings. <b><i>Methods:</i></b> Fifteen cases, both clinically and histologically consistent with GR, were selected and were subsequently analyzed to describe clinical and histological characteristics. <b><i>Results:</i></b> A total of 20 patients showed granulomatous infiltration in skin biopsies, but only 15 of them were clinically consistent with GR. Five patients who showed granulomatous inflammation were clinically consistent with erythematotelangiectatic or papulopustular rosacea. Among 15 patients, 13 (86.7%) were female and 2 (13.3%) were male. The most frequently involved area was the cheek, and none of the patients showed extrafacial lesions. There seems to be a possibility that treatment duration may be associated with the treatment response. <b><i>Conclusions:</i></b> This study confirms clinical characteristics of GR based on the diagnosis combining both clinical and histological findings.

Rosacea causing unilateral Morbihan syndrome

Morbihan syndrome is a rare entity causing woody induration of the face. There are numerous case reports of bilateral Morbihan syndrome. We present a case of a 46-year-old man with right infra-orbital cheek swelling and symptoms of rosacea who had histology consistent with granulomatous rosacea following debulking surgery. His clinical presentation and investigation findings support a diagnosis of rosacea causing unilateral Morbihan syndrome.
