purpose: to report the clinico-pathological and ultrastructural features of a case of meesmann corneal dystrophy (mcd). case report: a 10-year-old boy presented with decreased vision in both eyes since early childhood. slitlamp biomicroscopy disclosed diffuse intraepithelial microcystic changes in the cornea but other layers appeared unremarkable. high pathologic myopia and amblyopia were other...

To the Editor: We read with interest the article titled “A Histopathologic and Imaging Study of Verrucous Hemangioma” by Dr. Garrido-Ríos et al1 published in the November 2008 issue of Actas Dermosif iliográficas.1 It is difficult to establish retrospective diagnoses without clinical (and not just histologic) images of the primary lesion. The appearance and change in these images would provide ...

CLINICAL PRESENTATION A 42-year-old man presented with a 5-year history of an asymptomatic slow-growing papule on the left scapular region. The physical examination revealed a well-defined, 1.2-cm diameter, firm, domeshaped papule with a white-pinkish center, peripheral small papules with a pearly appearance, and a hyperpigmented outer rim (Fig 1). The initial clinical impression suggested basa...

it is known that pancreatic serous cystic tumors are uncommon pancreatic tumors. Grossly, they are more frequently microcystic or oligocystic [1]. The solid form is rarely described in literature. To our knowledge, only four cases of solid serous neoplasms have been described [2, 3, 4, 5] (Table 1). Herein, we present the fifth case of solid serous cystic neoplasm of the pancreas. She was a 59-...

A case is described of primary hyperparathyroidism in a patient with both a parathyroid cyst within the thymus gland and a concomitant parathyroid adenoma. The parathyroid adenoma contained microcystic areas of degeneration, and it is thought that the parathyroid cyst reflected degenerative change in a pre-existing adenoma. Parathyroid cyst should be considered in the differential diagnosis of ...

This paper describes a patient with previously normal corneas who underwent bilateral cataract surgery. This was followed by acute dehiscence of the epithelium and the eventual appearance of fingerprint lines, microcysts, and map-like areas typical of Cogan's microcystic dystrophy. Light and electron microscopy showed the presence of epithelial microcysts and a seam of subepithelial material li...

Cryptococcosis is a relatively common mycotic infection of the CNS caused by a ubiquitous saprophytic fungus. We present an unusual case of CNS cryptococcosis in an immunocompetent patient. Florid choroid plexitis resulted in the formation of intraventricular enhancing mass lesions that filled the ventricles and were hyperintense to associated periventricular edema on T2-weighted MR images. We ...

A case of microcystic adenoma (glycogen-rich cystadenoma) of the exocrine pancreas in a 62-year-old white female presenting with adult-onset diabetes mellitus is reported. Clinical, histopathologic, and ultrastructural findings are discussed with particular emphasis on the presence of myoepithelial cells, a morphologic feature not seen in this tumor previously. The controversy over diabetes mel...

Pancreatic serous cystadenoma can be categorized into microcystic, honeycomb, oligocystic, and solid patterns based on imaging appearance. The presence of typical computed tomography (CT) features helps to differentiate serous cystadenomas from other cystic and solid pancreatic masses. Cases with atypical features present a diagnostic challenge as they can mimic malignant neoplasms. This articl...
