Erythema nodosum leprosum necroticans: a case report of an atypical severe type 2 leprosy reaction and literature review.

Until now, leprosy remains a problem and challenge in the world because it can cause disability and morbidity in affected individuals, including problems due to the emergence of type 2 lepra reaction or erythema nodosum leprosum (ENL). The clinical picture of ENL can appear in an atypical and severe form, called ENL necroticans (ENN), which becomes a problem in diagnosis and therapy. We report a 17-year-old female with lepromatous leprosy and ENN who received therapy in the form of a combination of steroids and methotrexate.

Combination of cyclosporine A and methylprednisolone to treat pediatric Stevens-Johnson syndrome/toxic epidermal necrolysis overlap syndrome.

The treatment of epidermal necrolysis in pediatric patients remains a major challenge. Cyclosporine A has emerged as a promising therapy for epidermal necrolysis in adults; however, its efficacy in children is unclear. We present the case of a boy with Stevens-Johnson syndrome/toxic epidermal necrolysis overlap syndrome who was initially resistant to methylprednisolone monotherapy but improved after receiving the combination of cyclosporine A and methylprednisolone.

Modified Non-Cultured Cell Spray Induced Epithelization in LAMB3 Mutation Epidermolysis Bullosa.

Background: Autologous non-cultured cell (ANCC) spray has been used to treat burns, chronic wounds, and vitiligo, but its use in junctional epidermolysis bullosa (JEB) has not been published previously. Chronic wounds in JEB are caused by mutations of laminin 332 (L322), whose function is to attach and act as a glue in the basal membrane. It is proposed that ANCC applications can provide keratinocytes and fibroblasts required to improve epithelization and spontaneously correct revertant keratinocytes in the wound area.

Keloid-like Pilomatricoma of the Auricle: A Case Report and Review of Literature.

Pilomatricoma is a rare benign skin adnexal tumor arising from hair matrix cells. It usually manifests as a firm-to-hard, well-circumscribed, nontender nodule often mistaken as a dermoid cyst. However, its clinical presentation has been reported to mimic keloid.

Classical Type 1 Dendritic Cells Dominate Priming of Th1 Responses to Herpes Simplex Virus Type 1 Skin Infection.

CD4 T cell responses are crucial for the control of many intracellular pathogens, yet the requirements for their induction are not fully understood. To better understand the role that various dendritic cell (DC) subtypes play in CD4 T cell priming, we compared in vivo T cell responses to skin inoculation of mice with infectious or UV-inactivated HSV type 1. Localized infection elicited a Th1 response that was primed in skin-draining lymph nodes involving Ag presentation by migratory dermal and lymph node-resident DC.
