, the lesions are slightly elevated and uninflamed. The lesions can be removed with a shave biopsy, if desired. In black adults, a heavily pigmented variant, dermatosis papulosa nigra, occurs involving the malar region and often the eyelids. Keratoacanthoma appears similar to basal cell carcinoma and squamous cell carcinoma because it is elevated with a central ulcer crater. However, these dome-shaped tumors with rolled margins usually appear and rapidly grow in size (up to 1-2 cm) over a few weeks

is termed dermatosis papulosa nigra. Seborrheic keratoses vary in size and grow slowly. They may be round or oval and flesh-colored, brown, or black. They usually appear stuck on and may have a verrucous, velvety, waxy, scaling, or crusted surface. Seborrheic keratoses that are large, multiple, and/or rapidly developing can be a cutaneous paraneoplastic syndrome (Leser-Trélat sign) in patients who have certain cancers (eg, lymphoma, GI cancers).

FGFR3 and PIK3CA mutations in stucco keratosis and dermatosis papulosa nigra. Stucco keratosis (STK) and dermatosis papulosa nigra (DPN) are referred to as variants of seborrhoeic keratosis. However, the genetic alterations involved in the pathogenesis of these benign tumours are unknown.Because FGFR3 and PIK3CA mutations have been reported to be involved in the pathogenesis of seborrhoeic keratosis, we analysed whether these mutations are also present in STK and DPN.

A randomized, double-blind comparison of two topical anesthetic formulations prior to electrodesiccation of dermatosis papulosa nigra. Liposomal lidocaine 4% (L.M.X.4 cream, Ferndale Laboratories Inc., Ferndale, MI, USA) has been proposed as a more rapidly acting topical anesthetic than the eutectic mixture of lidocaine 2.5% and prilocaine 2.5% (EMLA cream, AstraZeneca LP, Wilmington, DE, USA) for venipuncture and laser procedures. However, their anesthetic efficacy has not been previously (...) compared for electrosurgical destruction of superficial skin lesions.To test the hypothesis that L.M.X.4 and EMLA differ in anesthetic efficacy when applied under occlusion for 30 minutes prior to electrodesiccation of papules of dermatosis papulosa nigra.Forty adults were randomly assigned to treatment with either agent for 30 minutes under Tegaderm.
