OBJECTIVE To examine microcystic inner nuclear layer (INL) changes in glaucomatous eyes and to determine associated factors. DESIGN Retrospective, cross-sectional, observational study. METHODS Two hundred seventeen eyes of 133 patients with primary open angle glaucoma (POAG), 41 eyes of 32 patients with preperimetric glaucoma and 181 normal eyes of 117 subjects were ultimately included. Mic...

Macular oedema typically results from blood-retinal barrier disruption. It has recently been reported that patients with multiple sclerosis treated with FTY-720 (fingolimod) may exhibit macular oedema. Multiple sclerosis is not otherwise thought to be associated with macular oedema except in the context of comorbid clinical uveitis. Despite a lack of myelin, the retina is a site of inflammation...

OBJECTIVE To describe a classification of microcystic lymphatic malformations of the tongue and to investigate different treatment methods. DESIGN Retrospective review of patients treated for microcystic lymphatic malformations of the tongue. Lymphatic malformations were classified into the following 4 groups according to their extent: isolated superficial microcystic lymphatic malformations ...

Although many head and neck surgeons agree that complete surgical excision is the treatment of choice for lymphatic malformation, the infiltrating nature of microcystic lymphatic malformations and the involvement of vital structures of the head and neck make total removal nearly impossible in most cases. Recently radiofrequency ablation was introduced for the treatment of microcystic lymphatic ...

We studied the expression of matrix metalloproteinases (MMP) and tissue inhibitors of matrix metalloproteinase (TIMP) in microcystic meningiomas to investigate a possible underlying mechanism for the development of microcysts and of peritumoral edema, which are frequent characteristics of this rare subtype. Between October 1995 and June 2004, 10 of 19 patients who had histologically confirmed p...

BACKGROUND Microcystic adnexal carcinoma, or sclerosing sweat duct carcinoma, is an uncommon cutaneous neoplasm associated with extensive local invasion. The standard of care with regard to the best excisional method in treating microcystic adnexal carcinoma has not been established. OBJECTIVES To perform a retrospective study comparing patients treated by Mohs micrographic surgery with those...

The rare neoplastic cystic adenomas of the pancreas form two groups of tumors: macrocystic mucinous and microcystic serous adenomas. Both entities show specific radiologic and histologic features. Several recent case reports, however, suggest some diversity within the group of microcystic serous adenomas. We present the case of a young man operated because of epigastric pain for 12 months and a...

In this issue of Brain, John Kisimbi et al. (2013) describe spectral domain optical coherence tomography (OCT) findings in a cohort of patients with Tanzanian endemic optic neuropathy, a disorder of unknown aetiology, leading to severe bilateral subacute optic neuropathy. They describe severe retinal nerve fibre layer (RNFL) thinning and concomitant microcystic macular changes in 12.5% of this ...

Tumors of the pancreas that contain substantial cystic components include mainly mucinous cystic neoplasm, intraductal papillary mucinous neoplasm, solid pseudopapillary tumor, and cystadenomas (which encompass microcystic, macrocystic/oligocystic, and rare solid serous adenomas). Microcystic adenoma of the pancreas is a tumor that is benign in nature. Malignant transformation in the tumor with...

OBJECTIVE To determine whether angiomatous and microcystic meningiomas which mimic high grade meningiomas based on extent of peritumoral edema can be reliably differentiated as low grade tumors using normalized apparent diffusion coefficient (ADC) values. METHODS Preoperative magnetic resonance imaging (MRI) of seventy patients with meningiomas was reviewed. Morphologically, the tumors were d...
