Reed nevus or pigmented spindle-cell nevus may mimic cutaneous melanoma; however, its dermoscopic and histopathological characteristics are different. This case report describes three patients with distinct clinical, dermoscopic and histopathological presentations, which were correlated to enable a differential diagnosis to be made between melanoma and Spitz nevus.
OBJECTIVES Melanocytic proliferations with Spitz differentiation present a difficult clinicopathologic dilemma, as their spectrum ranges from benign to malignant. Distinct entities include Spitz nevus, atypical Spitz nevus, and Spitzoid melanoma. Their histopathologic differentiation can be challenging, and cases of Spitzoid melanoma initially diagnosed as benign Spitz nevi are reported in the ...
We herein report an 11-year-old girl who came to our clinic with a swelling on the genital area of 2 months duration. Dermatological examination of the patient was performed and a pigmented lesion was found on the inner surface of the labium majus of the mucosa. The lesion was well circumscribed and approximately 1 cm in diameter, with homogenous color distribution. The patient was diagnosed as...
Combined melanocytic nevi are composed of 2 or more distinct populations of nevomelanocytes. Most commonly used to describe the combination of blue nevi with common nevi, it may also be applied to other combinations of benign melanocytic proliferations, including Spitz nevi and nevi with deep dermal pigmented nevomelanocytes. We report the incidence and distribution of these tumors at the Massa...
BACKGROUND Deep penetrating nevus (DPN) is a distinct variant of melanocytic nevus and remains a histopathologic challenge to pathologists because of its resemblance to blue nevus, malignant melanoma, pigmented Spitz nevus, and congenital melanocytic nevus. It often goes unrecognized due to its relative rarity. CASE PRESENTATION Here we report a case of DPN of the left anterior leg in a 51-ye...
Angio eccrine hamartoma (EAH) is a rare, benign tumoral lesion composed of glands and vascular structures in the mid dermis. We report on two observations Dakar. Observation 1: A four-month-old infant was seen for an erythematous plaque, rounded, with smooth surface, asymptomatic, localized to right thigh, evolving three months. The clinical appearance suggested spitz tumour. Cutaneous histolog...
A 23-year-old female presented with a reddish-brown dome-shaped hyperkeratotic nodule of 11 × 10 mm on the left lower leg. Dermoscopic examination demonstrated a prominent whitish scaly area with ring-like appearance, pinkish-white structureless areas, a few milia-like cysts, dotted and glomerular vessels, and light brown globules. The lesion was completely excised under the diagnosis of verruc...
