Optic nerve invasion of non-juxtapapillary uveal melanoma: a rare occurrence

A 44-year-old man presented with complaints of pain and discomfort in his left eye (OS). On examination, he had bare perception of light in OS and had a diffuse pigmented mass lesion in the nasal quadrant of the bulbar conjunctiva, associated with neovascularisation of the iris and iridocyclitis, with no fundus view. Intraocular pressure OS was 40 mm Hg. B-scan ultrasonography OS revealed an intraocular mass with thickened sclerochoroidal complex. A clinical diagnosis of OS ciliochoroidal melanoma with extraocular extension was made. He underwent OS extended enucleation with implant. Histopathological examination confirmed the diagnosis of ciliochoroidal melanoma with tumour extension into the optic nerve posteriorly and the extrascleral tissues anteriorly. There was no evidence of systemic metastasis. Even in a case of non-juxtapapillary uveal melanoma, poor vision and high intraocular pressure are clinical indicators of optic nerve tumour invasion.

Unusual occurrence of two sister tumours in the same patient- gastrointestinal stromal tumour and gastrointestinal autonomic nerve tumour

Gastrointestinal stromal tumours (GIST) account for less than 1% of gastrointestinal tumours, whereas Gastrointestinal autonomic nerve tumour (GANT) is a rare variant of gastrointestinal stromal tumour (GIST) and occurs at an estimated frequency of 1% of all malignant gastrointestinal tumours. We report the case of a 38-year old male which represents the rarity in the incidence of a Gastrointestinal Stromal tumour as well as the occurrence of a gastrointestinal autonomic nerve tumour together in the same patient which presented as a jejunal lump along with a terminal ileocecal intussusception. Multiple GISTs are associated with familial or hereditary syndromes are described only in few case reports whereas multiple sporadic GISTs have been rarely reported. This review aims to report the multiple sporadic occurrence of two types of GISTs as well as discuss highlight the features and prognosis of GANTs as surgeons and gastroenterologists are unaware of the existence of such an entity.
