The nature of breast dense core granules: uranaffin reactivity

In this study breast tissue that contained ultrastructural dense core granules has been examined from 24 patients. The possible neuroendocrine characteristics of the granules were studied using the uranaffin reaction and an ultrastructural argyrophil stain. The tissue included 15 breast carcinomas and nine benign samples. Two types of breast dense core granules can be distinguished on the basis of intracellular distribution patterns and histochemical reactivity. Type I dense core granules are the most common and they were found subluminally distributed in non-pathological tissues and benign lesions as well as carcinomas. They were uranaffin-negative and are unlikely to be of endocrine nature. Type II dense core granules were found only in four carcinomas, where they occurred abundantly throughout the cytoplasm. These granules were uranaffin-positive and argyrophilic and thus exhibited characteristics consistent with neuroendocrine structure.

Mycetoma of the calf

 Actinomycetous infections typically involve either the head and neck or the extremities following a traumatic implantation. Classic clinical associations are draining sinus tracts. This case report describes the pathologic and MR findings of a relatively acute mycetomatous process involving the soft tissues. Pathologic findings in this case included an occasional granule composed of gram positive, thin branching elements. These and other findings were consistent with actinomycetes bacterium infection. The discussion centers around the use of MR, both with and without gadolinium, in evaluating this type of granulomatous infection. Infiltration of the adjacent subcutaneous tissues was easier to appreciate on both the T1-weighted images without gadolinium and the T1-weighted images with gadolinium when compared to the T2-weighted images. Signal characteristics as described in this case report may suggest a granulomatous process.     

Professor Ahmed Shafik (1933–2007)

Most cases of anal abscess are caused by anal fistula and invasion of the surrounding tissues by a mixed colonic flora. Treatment consists of excision of the abscess and, in case of fistula, fistulectomy. Primary anorectal and perianal forms of actinomycosis are very rare and caused by actinomyces, as ubiquitous anaerobics bacterium. We report a case of perianal actinomycosis. The patient had a short history of painless perineal induration without fever and leukocytosis with normal results at routine blood examination. After excision, sulfur granules drained from the cavity and pathological investigations indicated perianal actinomycosis. Appropriate surgery and antibiotic treatment healed the perianal infection. After exclusion of possible diagnoses such as Crohn’s disease, tuberculosis and malignant growths, the rare case of perianal actinomycosis should be considered in the differential diagnosis of painless perianal masses.
