Nevus comedonicus is a type of hamartoma that arises from a developmental anomaly of the mesodermal part of the pilosebaceous gland. In most cases of nevus comedonicus, an acne-like skin condition develops. Repeated inflammation can cause a morphological change to the cyst, papule, to abscess. We experienced a case of congenital nevus comedonicus, which led to the formation of large multiple cy...
The so-called dysplastic nevus first entered medical parlance in 1980 [1], originally known as the B-K mole in 1978, only to evolve over the next 34 years into a variety of names including familiar and atypical sporadic mole, melanocytic nevus with persistent lentiginous melanocytic hyperplasia, junctional or compound nevus with architectural atypia/disorder with or without cytological atypia, ...
sebaceous carcinoma is a relatively rare cutaneous tumor that is most commonly derived from the sebaceous glands located in periorbital area. the extraocular occurrence of this tumor is very rare. we report a case of an 85 years old woman who presented with a slowly enlarging mass on the right temporal region. histological examination of the lesion revealed a malignant sebaceous carcinoma occur...
The purpose of this study was the clinical and histo-immunohistochemical analysis of two cases: a cutaneous pigmented facial malignant melanoma and a lumbar congenital nevus with malignant transformation. A series of clinical elements raised the suspicion of some malignant melanocytic lesions and the histopathological analysis through the paraffin embedding technique confirmed the clinical susp...
A high number of nevi is the most significant phenotypic risk factor for melanoma and is in part genetically determined. The number of nevi decreases from middle age onward but this senescence can be delayed in patients with melanoma. We investigated the effects of nevus number count on sentinel node status and melanoma survival in a large cohort of melanoma cases. Out of 2,184 melanoma cases, ...
Inflammatory linear verrucous epidermal nevus is a variant of verrucous epidermal nevus, characterized by recurrent inflammatory phenomena. Despite well-established clinical manifestations, the differential diagnosis between inflammatory linear verrucous epidermal nevus and linear psoriasis remains difficult. Clinical history, physical examination and histopathology analysis may not be sufficie...
A 16-month-old female presented with an extensive epidermal nevus demonstrating epidermolytic hyperkeratosis on histologic evaluation. Individuals with this disorder are at increased risk of bearing children with epidermolytic ichthyosis. This occurs because the same mutations causing cutaneous somatic mosaicism may also affect the gonads. Genetic counseling is advised for individuals with exte...
