Eosinophilic Granuloma.? Sarcoid of Boeck

Primary chiasmal sarcoid granuloma: MRI

Central nervous system (CNS) lesions, mainly involving the meninges, are found in up to 16% of autopsy studies of patients with known sarcoidosis [1]. Primary CNS sarcoid granuloma without systemic disease is seen in only about 5% of patients [2]. The characteristic MRI appearance of chiasmal sarcoidosis is peripheral contrast enhancement resulting from meningeal involvement. We report a rare c...

Eosinophilic granuloma of bone.

The sarcoid granuloma: ‘epithelioid’ or ‘lymphocytic-epithelioid’ granuloma?

BACKGROUND This study aims to analyze the structure and quantities of cellular elements in sarcoid granulomas. METHODS We investigated 34 transbronchial lung biopsy samples obtained from 34 sarcoid patients. The quantity and composition of the cellular elements inside a granuloma were determined by the quantitative stereometry method, employing the numerical density as a stereological method....

Traumatic granuloma/eosinophilic ulcer.

Two case reports of an uncommon type of oral ulcerative lesion are presented. These lesions are of long duration, benign and reactive, and may clinically mimic a malignant ulcer. Histologically, these are deep lesions which exhibit 'pseudoinvasion' into skeletal muscle. There is a predominance of eosinophils while other chronic inflammatory cells such as plasma cells and histiocytes are in abun...

[Orbital eosinophilic granuloma].

PURPOSE To report the retrospective experience of a reference center in the diagnosis and treatment of orbital eosinophilic granuloma. METHODS A review of the files in the Opththalmic Pathology Laboratory, of the Hospital Universitário Professor Edgard Santos, Universidade Federal da Bahia, between 1974 and 2004, was conducted to identify cases of orbital eosinophilic granuloma. Data of diagn...
