Histopathological Type

Congenital cholesteatoma is a whitish mass in the middle ear medial to an intact tympanic membrane. It is often without symptoms and therefore incidentally diagnosed. Pediatric congenital cholesteatoma generally starts as a small pearl-like mass in the middle ear cavity that eventually expands to involve the ossicles, epitympanum, and mastoid. The location, size, histopathological type, and extent of the mass must be evaluated to select the appropriate surgical method. Although microscopic ear surgery has traditionally been performed to remove congenital cholesteatoma, a recently introduced alternative is endoscopic surgery, which allows a minimally invasive approach and has better visualization. Here, we report the first known case of a patient with congenital cholesteatoma in the anterior epitympanic recess and discuss the utility of an endoscopic approach in the removal of a congenital cholesteatoma in the hidden area within the middle ear.

Abstract Nodular hidradenoma is an uncommon cutaneous adnexal tumor arising from sweat glands. In the skin, it usually presents as a solitary dermal nodule; excision is curative in most cases. In rare instances, it may present as a breast mass and can mimic breast carcinoma clinically and radiologically, causing diagnostic dilemmas for the treating physician and pathologist. Herein, we discuss a case of nodular hidradenoma in a 20-year-old Hispanic woman as a rapidly growing mass in the breast that mimicked breast carcinoma. We discuss the rare presentation of this uncommon tumor and the differential diagnosis of this entity, as well as the results of our literature review on the topic.

The authors report an extremely rare case of spinal intraosseous epidural arteriovenous fistula (AVF) with perimedullary vein reflux causing symptoms of myelopathy. The intraosseous fistula tracts were completely obliterated with Onyx embolic agent, resulting in a total resolution of symptoms. The unique features of this case include the rare location of the fistula in the vertebral body and the association of the fistula with a compressive fracture. Imaging studies confirmed these hemodynamic findings and provided clarity and direct evidence regarding the association of epidural AVF formation with the vertebral compressive fracture. The authors also propose a possible disease evolution based on the previously adduced reflux-impending mechanism.

Uncommon Tumor

Adrenocortical carticnoma (ACC) is an uncommon tumor with an incidence of 1-2 cases/million/year. It has two peak incidences; the first one in the first decade and the second one in the fourth decade. Most patients present with features of steroid hormone excess or abdominal mass effects, but about 15% of ACC are diagnosed incidentally. It is hormonally functional in 80 - 100% patients and the predisposing lesions include congenital adrenal hyperplasia and adenoma. ACC has significant syndromic and genetic association. Surgery offers the best chance of cure, especially in localized disease. Here, we present the case of virilization in a young female child secondary to a functioning ACC. The child had classical hormonal and imaging features of functioning ACC and underwent resection of the tumor (Adrenalectomy) with good outcome.

Fibrous Tumor

Solitary fibrous tumors are uncommon spindle cell neoplasms generally associated with serosal surfaces, especially the pleura. Recently, these tumors have been documented in a number of extrapleural sites including the head and neck. So far only two cases of parapharyngeal solitary fibrous tumor have been reported in the English literature. Rare location of an uncommon lesion often gives rise to difficulty in diagnosis or to misdiagnosis. In both the previously reported cases, as well as in our case, the diagnosis of solitary fibrous tumor was not made until the excised tumor was subjected to histopathology and immunohistochemistry.
