Reed Nevus (Pigmented Spindle Cell Nevus) in an 11-Month-Old Japanese Infant
Reed nevus (pigmented spindle cell nevus) is a nevus with the histopathological features of abundant melanin, monomorphic spindle-epithelioid melanocytes, spindle cell nests confined within the epidermis and papillary dermis, and occasional upward interepidermal progression of melanocytes. Here, we reported an unusual case of Reed nevus in an 11-month-old Japanese male infant. Infantile Reed ne...
متن کاملReed nevus (pigmented spindle-cell nevus): a report of three cases with distinct dermoscopic patterns.
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.
متن کاملTraumatic iridial extrusion mimicking a conjunctival melanocytic neoplasm
Conjunctival melanoma is a rare malignant tumour of the eye. Its diagnosis represents a challenge for general pathologists due to low exposure to ocular biopsies and a broad differential diagnosis. In addition, conjunctival samples are often small and are associated with a high frequency of artefacts due to their processing. Here, we present the first case to date of a traumatic iridial extrusi...
متن کاملExpression of microphthalmia transcription factor, S100 protein, and HMB-45 in malignant melanoma and pigmented nevi
Malignant melanoma (MM) is a type of malignant tumor, which originates from neural crest melanocytes. MM progresses rapidly and results in a high mortality rate. The present study aims to investigate the expression of microphthalmia transcription factor (MITF), the S100 protein, and HMB-45 in MM and pigmented nevi. A total of 32 MM samples (including three skin metastasis, three lymph node meta...
متن کاملAdenoma of the non-pigmented epithelium of the ciliary body with smooth muscle differentiation: a unique case report
Adenoma of the non-pigmented epithelium of the ciliary body (ANPCE) is a relatively uncommon lesion usually presenting in the non-pigmented epithelium of the ciliary body, which belongs to the neuroectodermal origin. Histologically, this tumor consisted of sheets, cords, and tubules occasionally forming glandular configurations. The cells of the tumor had abundant eosinophilic cytoplasm with ro...
