IntroductionTinea capitis is a common infection of the scalp and hair caused by dermatophyte fungi that principally affects children1. It is an uncommon infection in adults and generally occurs in postmenopausal women and immunocompromised patients. Adult tinea capitis may have atypical clinical presentations2 34. The causative pathogens in children and adults belong to two genera: Trichophyton andMicrosporum 5. The clinical manifestations characterized by an erythematous and scaly plaques, itching, suppurative swelling with purulent discharge, areas of alopecia and regional lymphadenopathy. It is often misdiagnosed as a bacterial infection, leading to unnecessary antibiotic prescription or surgical intervention. Treatment delay may result in permanent hair loss6 7. The diagnosis of tinea capitis is made by fungal culture (gold standard), microscopy, wood’s lamp and trichoscopy5 8.

The patients' discouragement from presentation due to the COVID-19 pandemic resulted in the progression of many manageable diseases to a critical condition. we report a case of carbuncle promotion to the necrotizing fasciitis in the context of undiagnosed diabetes mellitus and delay in visiting physicians due to fear of COVID-19.

Keratosis lichenoides chronica (KLC) is a rare dermatosis which represents different clinical characteristics between adult- and pediatric-onset cases. We described a childhood case of KLC with features typical for adult onset disease. Acitretin led to partial improvement of her skin (but not mucosal) lesions.
