BACKGROUND: occasional case reports have described the appearance of Kaposi's sarcoma (KS) on previously unaffected skin after incidental or accidental injury, but the association is probably under-reported. OBJECTIVES: to present a large case series of patients suffering from Koebner phenomenon (KP) in KS and describe their main epidemiological, clinical, and therapeutic features. METHODS: we have retrospectively analyzed our clinical and photographic records of 524 patients who had been diagnosed with KS between 2009 and 2021. RESULTS: 31 of 524 (6%) KS patients developed KP. Among these 31 patients, 24 (77%) had KS lesions after surgery, 4 (13%) after electrochemotherapy, laser therapy and cryotherapy, and 3 (10%) on areas affected by bullous diseases. CONCLUSIONS: trauma, including surgery or other medical procedures, can trigger KS, underlying the importance of treatment options which cause the least injury to the skin.

INTRODUCTION: pemphigus vulgaris is a rare autoimmune blistering disease that involves the skin and mucous membranes and rarely occurs in pediatric age. METHODS: we present a case of childhood pemphigus in a 9-year-old patient from Burkina Faso, which initially manifested with erosive lesions symmetrically distributed in the oral cavity. After a few months, we also observed hyperchromic lesions of the back. Histopathological examination of skin samples showed intraepidermal acantholysis, while direct immunofluorescence showed deposits of complement (C3) and immunoglobulins G (IgG) in the epidermidis; an ELISA test highlighted the presence of circulating autoantibodies against desmoglein 3. RESULTS: the follow-up of this patient was made difficult by the advent of the COVID-19 outbreak. However, after about one year of combined therapy with systemic steroids and azathioprine the patient reached clinical remission.
