Collision tumors are characterized by the coexistence of two cancers in the same anatomical site and its pathogenesis remains controversial. Although uncommon, the association of basal cell carcinoma and melanocytic nevus is the most common among combinations of skin tumors. Even rarer is the association of two malignant tumors. We report a case of tumor collision representing melanoma and baso...

Sturge Weber syndrome is a rare sporadic neurocutaneous syndrome. It has extra -oral manifestations mostly in form of unilateral port wine stain on face that are ipsilateral to intra-cranial lesions (mostly lepto-meningeal angioma), seizures, glaucoma and intra-orally by hemangioma gingiva. We case report child with facial nevus opposite lesion, intra-oral gum hypertrophy. Other than contralate...

We investigated in detail the dermoscopic and histopathological findings in a case of a superficial type of multiple basal cell carcinomas (BCCs). These multiple lesions (occurring in the chest, neck, and back) showed three different findings, respectively. Dermoscopy of the erythematous and brown-colored patch on the anterior chest showed spoke wheel areas, and the histopathological cross-sect...

Nevus sebaceous of Jadassohn is a congenital hamartoma that usually affects the scalp and face. Several benign or malignant neoplasias may develop in the lesion and the most common are trichoblastoma, syringocystadenoma papilliferum, and basal cell carcinoma. Trichilemmoma is a benign solid tumor originating from external sheath cells of pilosebaceous follicles. When it is characterized by a ce...

We explore the diagnostic potential of imaging endogenous fluorophores using two photon microscopy and fluorescence lifetime imaging (FLIM) in human skin with two spectral detection channels. Freshly excised benign dysplastic nevi (DN) and malignant nodular Basal Cell Carcinomas (nBCCs) were excited at 760 nm. The resulting fluorescence signal was binned manually on a cell by cell basis. This i...

Linear epidermal nevi frequently follow the lines of Blaschko and may be confused with the verrucous stage of incontinentia pigmenti. Inflammatory epidermal nevus appears as a line array of pink to red papules usually on the lower limb (Buttock and hip) clinically resembling psoriasis or eczematous dermatitis. But inflammatory epidermal nevus has distinct histopathologic features. We report a c...

Odontogenic keratocysts (OKCs) are one of the most frequent features of nevoid basal cell carcinoma syndrome (NBS). It is linked with mutation in the PTCH gene. Partial expression of the gene may result in occurrence of only multiple recurring OKC. Our patient presented with nine cysts with multiple recurrences over a period of 11 years without any other manifestation of the syndrome.

blue rubber bleb nevus syndrome is a rare disorder that is characterized by multiple recurrent vascular malformations of skin and gastrointestinal tract . the affected patients may present with diverse manifestations including iron deficiency anemia. we report this syndrome in a 22-year-old man that was referred to our hospital for iron deficiency anemia with unknown cause and vascular malforma...
