herein we describe a case of intraocular melanoma in a17-year old leukemic patient.   the history, histological findings of the enucleated eye, blood and bone marrow of the patient were investigated. the enucleated eye contained epitheloid cell type melanoma instead of leukemic cell infiltration.  we conclude that intraocular malignant melanoma can occur in acute lymphoblastic leukemia.

BACKGROUND Primary malignant melanoma of the esophagus (PMME) is a rare disease with a poor prognosis. There are few reports of early-stage cases in which tumor invasion reached the lamina propria or muscularis mucosae, as in the present case. A standard treatment for early-stage PMME has not yet been established. The present study aimed to summarize previous reports and to discuss the indicati...

background: malignant melanoma, one of the most deadly skin cancers, is a skin tumor that arises from the epidermal melanocytes. the aim of this study is to evaluate the demographic and clinical data of malignant melanoma patients in a referral dermatology center in the south of iran. methods: in this retrospective study, we have reviewed files of 116 patients diagnosed with malignant melanoma ...

introduction: caustic ingestion is responsible for a spectrum of upper gastrointestinal tract injury from self-limited to perforation. this study conducted to evaluate clinical characteristics as well as surgical outcomes in patients with caustic ingestion.   materials and methods: between nov1993 to march 2011, 14 adults with a clinical evidence of corrosive ingestion were admitted into our in...

 Abstract Background: Esophageal replacement is indicated in certain circumstances including long gap esophageal atresia, severe strictures due to gastro-esophageal reflux (GER) and caustic burns. We analyzed our results of 18 patients who underwent esophageal replacement in our university hospital. Methods: We reviewed esophageal replacements carried out in our department between June 1996 and...

gastrointestinal melanoma (gim) is occasionally observed in general practice. we report a case of melanoma dispersed diffusely in the stomach and duodenum with no skin involvement.

Malignant melanoma in the esophagus is a rare condition which has been described only occasionally in case reports or in larger series of patients with esophageal disease. We describe here the very rare case of a patient who presented initially with a 2-month history of dysphagia and weight loss which led to the endoscopic diagnosis of an unclear lesion in the distal esophagus. Biopsies were ta...

amelanotic melanoma is a variant of malignant melanoma comprising 2% to 8% of all malignant melanomas. the amelanotic presentation of melanoma in the oral cavity is extremely rare and has been reported only occasionally in the literature. moreover, the lack of melanin makes these tumors difficult to diagnose than that of pigmented lesions and the prognosis tends to be poorer. herein, we report ...

The incidence of cutaneous melanoma is increasing worldwide, especially for thin melanoma (Breslow ≤1 mm). Thin cutaneous melanoma has a favorable prognosis but there are few data about the prognosis of patients with ultra-thin cutaneous melanoma (Breslow ≤ 0.5 mm). Our aim was to investigate the disease-free survival among patients with invasive cutaneous melanoma with Breslow ≤ 0.5 mm after 1...
