TWEAK Progress in Dermatology: A Review

Tumour necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) is a member of the TNF superfamily (TNFSF). It acts through its receptor fibroblast growth factor-inducible 14 (Fn14). Studies have indicated that TWEAK/Fn14 pathway activation controls multiple cellular responses, including proliferation, angiogenesis and induction of inflammatory cytokines. TWEAK/Fn14 is manifested in many tissues of our body and most importantly in the skin causing inflammation and many autoimmune and neoplastic cutaneous disorders. Evidence suggests that the TWEAK/Fn14 axis, the downstream signalling pathway and its inflammatory molecular expressions are involved in the pathogenesis of many cutaneous disorders such as psoriasis, atopic dermatitis (AD) vitiligo and melanoma. So, this literature review describes a brief introduction of TWEAK and TWEAK/Fn14 pathway and summarises the case-series and open-label studies performed in the field of dermatology and its potential therapeutic benefit.

Co-occurrence of progressive hemifacial atrophy due to morphea with homolateral segmental vitiligo: A case report

Simultaneous occurrence of progressive hemifacial atrophy due to morphea and homolateral segmental vitiligo, younger onset, rapid progression followed by stabilization and dermatomal distribution suggests a possible relationship between them.

Multiple Acquired Elastotic Hemangioma in a Single Patient: A Case Report

Acquired elastotic hemangioma is a hemangioma variant which was first described in 2002. Usually it is characterized by being a benign, solitary, slow growing lesion and associated with solar exposure but here we discuss a case of 50 years old male from Australia, who had multiple pigmented and violaceous lesions on the back which he had noticed for 5 years. The cases of multiple lesions are reported few in the literature. The lesions had characteristic clinical dermatoscopic feature showing typical violaceous lesions with widespread shiny white structure without any vessels. Histopathology revealed band like proliferation of blood vessels involving superficial dermis arranged horizontally parallel to the epidermisalong with elastosis in dermis. Treatment was done through surgical excision with no relapse reported.
