The predisposition to epithelial neoplasms in nevus sebaceous is well established; most tumors occur in adults and are benign. Hidradenoma is a relatively rare benign tumor of sweat gland origin that can rarely arise within a nevus sebaceous. We present an interesting case of a hidradenoma and sebaceoma arising within a nevus sebaceous and present a literature review of the 2 conditions. Even t...
Malignant melanoma and basal cell carcinoma are more common over a preexisting nevus. But squamous cell carcinoma over a nevus is a rare phenomenon. A 55-year-old male presented with a slow growing noduloulcerative lesion on a preexisting nevus over scalp. For that he had undergone excisional biopsy. Biopsy came out to be a squamous cell carcinoma with lateral margin positive for tumor. So post...
absract intracranial invasion of cellular blue nevus (cbn) from the skin is extremely rare and such a condition with malignant transformation is even rarer. a case of meningeal melanoma with malignant transformation which was derived from an ota nevus is presented in this report. a21-year-old man with a neurocutaneous syndrome since childhood was referred with headache and mild left hemiparesia...
BACKGROUND Apoptosis is important for maintenance of tissue homeostasis and often dysregulated in cutaneous neoplasms. The apoptosis inhibitor survivin is expressed in melanoma and non-melanoma skin cancers and benign keratinocytic lesions. Its expression has not been studied in melanocytic nevi. OBJECTIVE We determined the expression pattern of survivin in benign melanocytic nevi in comparis...
Inflammatory linear verrucous epidermal nevus and linear psoriasis are sometimes hard to differentiate clinically and pathologically. Although immunohistochemical expression of keratin 10 (K10), K16, Ki-67, and involucrin may be useful for differentiating both entities, these results have been reported in only a few cases. We collected data from 8 patients with inflammatory linear verrucous epi...
IMPORTANCE Recognition of posterior scleral bowing with choroidal nevus is essential to avoid an underestimation of tumor thickness. OBJECTIVE To describe a particular observation of posterior scleral bowing associated with choroidal nevus on enhanced-depth imaging (EDI) optical coherence tomography (OCT). DESIGN, SETTING, AND PARTICIPANTS Retrospective observational case series at a referr...
Nevus of Ota is a macular discoloration the face which most commonly found in Japanese and females are more affected than males. It first described by Tanino 1939, involves skin along distribution second division trigeminal nerve. Involvement palatal mucosa occurs rarely nevus Ota, it usually blends with oral typically irregular, undefined often present as mottled patch. We describe here case i...
Nevus lipomatosus superficialis is a rare type of connective tissue nevus. Cylindroma is a benign skin appendage tumor with a predilection for the scalp of older females. We describe the case of a 56-year-old woman with a scalp lesion demonstrating histopathologic features consistent with benign cylindroma arising within a nevus lipomatosus superficialis. To our knowledge, this lesion has not b...
INTRODUCTION Prostatic blue nevus was first described as a benign lesion of uncertain and controversial histogenesis by Nogogosyan in 1963. Currently, 30 cases have been reported in the world literature. CASE PRESENTATION A 63-year-old Hispanic man presented with prostatism of several months' evolution. Histopathological examination revealed a blue nevus associated with nodular hyperplasia an...
The external auditory canal is an uncommon location for the nevi that are common benign tumors of the skin. A papillomatous lesion was detected in the external auditory canal of the patient who was on follow-up for acute otitis externa. The lesion which resembled a nevus was excised and was diagnosed as an intradermal nevus in pathological examination. The clinical and pathological picture of t...
