Ingia / Ingia

BACKGROUND Melanosis coli is a benign lesion affecting the mucosa of the large intestine. There is a relationship between the presence of melanosis and anthraquinone laxative use. Melanosis coli is also observed in patients with colon cancer, but there is doubt whether these two conditions are

Association of Conjunctival Dysplasia (Squamous Intraepithelial Neoplasia) with Melanosis (Microscopic Non- Proliferative Melanin Pigmentation)

Ingia / Ingia

Melanosis was found to various extents in a wide array of tissues of all 23 autopsied mice whose transgene consisted of the tyrosinase promoter fused to the simian virus 40 early-region oncogenic sequences. Pigmentation in a given animal was attributable to any or all of the following; an increase

Nodular melanosis due to epithelial neoplasms: a finding not restricted to regressed melanomas.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Nodular or tumoral melanosis consists of nodular or sheetlike deposits of melanophages in the dermis. When nodular melanosis is present, a completely regressed malignant melanoma is a major diagnostic consideration. We present a case of nodular melanosis due to regression of a pigmented basal cell

Ingia / Ingia

BACKGROUND Melanocytic meningeal tumours are rare extra-axial neoplasms of the nervous system, with only three reported cases in the cavernous sinus. Herein we describe for the first time the association of ocular melanosis and multiple intracranial melanocytic meningeal tumours, with the presenting

Ingia / Ingia

The present study aimed to investigate the proteomic difference between melanosis coli (MC) alone and melanosis coli with colon cancer (MCCC). Protein expression in patients with different diseases was analyzed using two-dimensional gel electrophoresis and matrix-assisted laser desorption

Dysphagia, melanosis, gastrointestinal stromal tumors and a germinal mutation of the KIT gene in an Argentine family.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Gastrointestinal stromal tumors (GIST) are the most common mesenchymatous neoplasms of the human digestive tract. They locate preferentially in stomach, duodenum or small bowel. Usually sporadic, familial cases unrelated to neurofibromatosis may be due to germline mutations in KIT or PDGFRA. We

Melanosis coli in two patients with colorectal neoplasia.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Melanosis coli is characterized by pigment deposition in the lamina propria and caused by increased epithelial apoptosis. Chronic laxative use induces melanosis coli and possibly increases colorectal cancer risk. We report on two cases of melanosis coli, one with colorectal carcinoma and the other

Intramedullary and retroperitoneal melanocytic tumor associated with congenital blue nevus and nevus flammeus: an uncommon combination of neurocutaneous melanosis and phacomatosis pigmentovascularis--case report.

Ingia / Ingia

Neurocutaneous melanosis (NCM) is a rare condition characterized by central nervous system melanocytic tumors associated with congenital melanocytic nevi. Phacomatosis pigmentovascularis (PPV) is an association of vascular nevus with pigmentary nevus. Aberrant maturation of neural crest-derived

Coexisting intracranial meningeal melanocytoma, dermoid tumor, and Dandy-Walker cyst in a patient with neurocutaneous melanosis. Case report.

Ingia / Ingia

Neurocutaneous melanosis (NCM) associated with Dandy-Walker malformation is a very rare congenital neurodysplasia with the same origin. Primary intracranial melanocytic and dermoid tumors are also benign congenital lesions that usually arise from the leptomeninges and are formed by the inclusion of
