A histopathological examination of an EN-like lesion with a few pustules revealed dense perivascular and periglandular infiltrates throughout the dermis and subcutis, which were composed of neutrophils, histiocytes, lymphocytes, and a lot of cell debris with marked necrobiotic changes. Immunohistochemically, cytotoxic CD8⁺ cells were much more common than CD4⁺ cells in the dense neutrophilic infiltrates. Many CD68⁺ macrophages were present around the CD8⁺ cells.

Mycobacterium stephanolepidis is a rapidly growing mycobacterium, closely related to Mycobacterium chelonae. It was first reported in 2017, and whether it is infectious to humans is unknown. Here, we report a rare case of cutaneous M. chelonae infection requiring a differential diagnosis of M. stephanolepidis infection.

Hypertrophic lupus erythematosus (HLE) remains pose a treatment challenge, and often displays disfiguring scar with cosmetic and/or functional impairment. We report a male case of refractory hypertrophic lupus erythematosus on the face, whose disease activity was controlled with a combined use of topical and systemic immunosuppressants, and hydroxychloroquine. The persisted, irreversible fibrotic skin mass was finally treated with surgical approach using full-thickness skin graft, achieving a favorable cosmetic result.
