Multicenter Retrospective Andalusian Study of the Use of Sonidegib for the Treatment of Local Advanced Basal Cell Carcinoma in Real Clinical Practice.

Introduction: Locally advanced basal cell carcinoma (LA-BCC) is defined as that BCC in which there is radiological confirmation of invasion of certain neighboring structures in depth and also, usually, a BCC that is of a sufficient size and invasion (although there is no radiological demonstration of deep invasion) in which surgery and radiotherapy are not adequate, are insufficient or are contraindicated to achieve the cure of the tumor, either due to characteristics of the tumor itself or of the patient. Sonidegib is indicated for the treatment of adult patients with locally advanced basal cell carcinoma that is not amenable to curative surgery or radiotherapy.

Material And Methods: This is a retrospective, multicenter and descriptive study in nine centers in Andalusia, Spain.

Rituximab for the treatment of lupus erythematosus panniculitis.

Lupus erythematosus panniculitis (LEP) or lupus profundus (LP) is a clinical variant of lupus eryhematosus that involves the deep dermis and the subcutaneous fat and is associated with tender subcutaneous nodules or plaques, with occasional ulceration, atrophy, and scarring. The management of this entity can be difficult because of the lack of response to conventional treatments, such as systemic steroids and antimalarials. The two patients of this study presented LP refractory to several therapies that demonstrated a remarkable improve to the infusion of the anti-CD20 monoclonal antibody, rituximab at a dosage of 375 mg/m²/week.
