"Unraveling the Uncommon: A Case Report of Cholinergic Urticaria Associated with Pityriasis Versicolor in a Postmenopausal Woman"

Abstract

Pityriasis versicolor characterized by pigmentary changes due to Malassezia yeast colonization, is a common cutaneous fungal infection. However, its association with cholinergic urticaria is rare. We present a case of a 52-year-old postmenopausal woman with persistent sore throat and hypopigmented, scaly lesions on her arms and thighs, accompanied by severe Pruritis. Concerns regarding hormonal changes post-menopause prompted consultation with an allergist. Referral to a dermatologist revealed cholinergic urticaria associated with pityriasis versicolor, a rare fungal infection. Treatment with luliconazole, fluconazole, and cyproheptadine led to a significant improvement in her symptoms. This case highlights the importance of considering uncommon presentations and interdisciplinary collaboration in managing complex dermatological conditions.
