IntroductionSubungual onycholemmal cysts (SOC) also known as subungual epidermoid inclusion cyst is an uncommon nail abnormality which affect the dermis of the nail bed. SOC has variable clinical presentations include onychodystrophy, ridging, clubbing, thickening, pigmentation or even appears normal (1). It can also mimic different nail malignancy such as melanoma, SCC or glomus tumor (2). In this report we document a case of unilateral second right finger nail onychodystrophy in 54-year-old man.

Propionibacterium acnes is a typical component of the human body's flora and has been implicated as the causative infectious agent following a variety of medical operations. We present a case of a 21-year-old male with severe global acneiform eruption with a non-healing limb lesion near the orthopedic surgery incisions.

a 45‑year‑old male patient that presented with a verrucous hyperkeratotic plaque on the lower lip mimicking Squamous Cell Carcinoma. However, oral examination revealed, reticulated white patches on the bilateral buccal mucosa, and a biopsy of the lip lesion revealed lichenoid dermatitis which led to the diagnosis of hypertrophic lichen planus

The COVID-19 pandemic is a major health issue and patients with underlying conditions are more susceptible to catastrophic outcomes. Toxic epidermal necrolysis (TEN) is a severe systemic disease caused by immune system hypersensitive reaction. We present a case of TEN that later complicated with COVID-19,Deep Vein Thrombosis(DVT),Pulmonary Emboli(PE),and death.

The most common variant of cutaneous T-cell lymphomas (CTCL) is mycosis fungoides (MF).The spontaneous regression (SR) of MF is rare. Here, we are reporting an interesting case of refractory MF after COVID-19. The SARS-CoV-2 could be an essential component in the improvement of clinical features related to MF.

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.
