Nevus sebaceus can give rise to multiple neoplasms, some of which have the potential to become malignant. We describe the occurrence of a previously unreported combination of a cutaneous horn proliferating from a trichilemmoma overlying a multilocular pilar cyst and nevus sebaceus. An elderly woman with a several years’ history of multiple scalp subcutaneous nodules and an enlarging cutaneous h...

Background: Epidermal nevus is a common skin hamartoma. Its definite treatment is difficult and in most cases the disease has recurrence. Objective: Evaluation of topical tretinoin 0.05% and 5 Fluorouracil (5FU) 5% in the treatment of epidermal nevus. Patients and Methods: Fifteen patients with epidermal nevus referred to skin clinic in Razi Hospital in Tehran whose diagnoses were confirm...

We report phakomatosis pigmentovascularis (PPV) detected in a 40- year-old male characterized by the presence of a port-wine stain in the background of aberrant Mongolian spots covering the back, nevus of Ota, ocular melanosis, epidermal nevus and a scaly patch with the diagnosis of discoid lupus erytematosus. These associations have not been reported yet.

We present a 6-week-old female infant from the Lao People's Democratic Republic with a large, red, exophytic scalp mass and numerous flesh-colored verrucous plaques on her face and the right half of her body since birth. The clinical and pathological findings are consistent with the new phenotype of the large, polypoid types of nevus sebaceous.

Syringocystadenoma papilliferum (SP) commonly arises in conjunction with nevus sebaceous. Other less common lesions reported with SP include apocrine adenoma, condyloma acuminatum, hidradenoma papilliferum associated with hidrocystoma, poroma folliculare, and a single case ofverrucous carcinoma. We report the second case of verrucous carcinoma in conjunction with SP.

Nevus sebaceous (NS) is a type of classical nevus or congenital malformation that is often present at birth and commonly involves the scalp or face. The lesion usually presents as a linear, yellow, hairless, and verrucous plaque. It has been well-established that several benign and malignant tumors can develop from the NS; however, there have been no reports about ectopic fat cells in the dermi...

Objective To study the clinical and histopathological features of nevus sebaceous (NS). Methods We selected 20 cases of nevus sebaceous for clinical and histopathological evaluation. Results Regarding the clinical appearance of lesions verrucous plaques were seen in 60% patients, papules in 25% and patches in 15%. All of the lesions showed abortive/immature hair follicles characterized by cords...
