Keywords:

Introduction: Mansoni’s piosis is an uncommon variant of bullous impetigo characterized by its localization in skin folds, particularly the axillae and groin. Literature on the condition is scarce and limited to isolated case reports.
Objective: To describe the clinical and epidemiological characteristics of a series of 5 cases of Mansoni’s piosis treated at the Dermatology Department of the General Calixto García University Hospital.
Case presentation: Five adult patients (3 men and 2 women), aged 26 to 56 years, with no relevant medical history, are presented. All sought consultation for bullous lesions in the axillae—present for 3 to 7 days—associated with excessive sweating and exposure to high temperatures. Physical examination revealed flaccid bullae containing purulent fluid, as well as erosions with a collarette of scales and crusts. Microbiological cultures were positive in all cases, identifying Staphylococcus aureus in 5/5 and Streptococcus pyogenes in 3/5. Combined treatment with Bidens pilosa (romerillo) compresses, topical gentamicin, and oral cephalexin proved effective, resulting in complete resolution within 8 to 12 days without complications or recurrences.
Conclusions: This series of 5 cases confirms the clinical characteristics described in classical literature but provides new observations regarding associated symptoms (pruritus and burning sensation) and mixed etiology. Microbiological confirmation in all cases and the favorable response to treatment enhance the understanding of this rare entity.
