This case report describes a 53-year-old obese female with pruritic trichostasis spinulosa (TS) presenting with itchy lesions on her breasts and lower abdomen, an unusual site for TS. Diagnosis was confirmed through dermoscopy and histopathology. Treatment with topical tretinoin, oral antihistamines, and antibiotics led to significant improvement in 6 weeks. The report highlights the need to consider TS in atypical locations and the effectiveness of noninvasive diagnostic tools, while also noting the challenges in diagnosing and treating the pruritic variant of TS.
