Blue nevus is an uncommon pigmented tumor of dermal melanocytes that has traditionally been classified into common and cellular variant. It is usually a skin tumor in adults but can become apparent in early childhood or even be present at birth. Malignant blue nevus is a rare melanocytic tumor of

OBJECTIVE
To study the induced change of tumor necrosis factor alpha (TNF-alpha) level in serum and colon tissue of guinea pig model with melanosis coli and its significance induced by rhubarb (RB).
METHODS
One hundred and twelve guinea pigs of clean grade were randomly divided into four groups: the

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)

Purpose: To determine the association between conjunctival epithelial dysplasia (squamous intraepithelial neoplasia) and its melanosis (microscopic non-proliferative melanin pigmentation) in conjunctival biopsies.

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.

Logáil Isteach / Cláraigh
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
Intracranial melanocytic meningeal tumours and melanosis oculi: case report and literature review.

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

BACKGROUND
Eye and skin share the embryological origin. Both are established risk factors in epidermal skin cancer. There are few reports using iris colour classification scales, most of them analyse colour in general or are too complex to use in daily practice.
OBJECTIVE
To investigate which iris

Logáil Isteach / Cláraigh
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

Logáil Isteach / Cláraigh
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
