Hibernoma arising in the breast is rare and may present as an asymptomatic mass or may be detected by screening mammography. Four histologic types have been identified: typical, myxoid variant, spindle cell variant, and the lipoma-like variant. The most common “typical variant” is composed of pale to eosinophilic multivacuolated cells with interspersed univacuolar cells. Hibernomas are universally benign and are not known to recur or have an aggressive behavior, even in incompletely excised lesions. Hence, their clinical importance lies in distinguishing them from other benign and malignant breast neoplasms as well as inflammatory conditions that come into the histologic or radiologic differential. This review discusses the clinical features, radiologic and histopathologic characteristics, ancillary studies, suggested pathogenesis, differential diagnosis, and treatment of and prognosis for these uncommon lesions.

Angiolipoma is a benign tumor composed of adipose tissue and proliferating blood vessels that is commonly found in the subcutaneous tissue of the trunk and extremities. Gastric angiolipoma is a rare entity, and to the best of our knowledge, only 4 cases have been reported in the English-language literature thus far. These tumors may present as gastrointestinal bleeding and anemia or with obstructive symptoms. Accurate preoperative diagnosis is challenging because of nonspecific clinical symptoms and lack of specific findings on imaging studies. The correct diagnosis is usually made by histopathologic examination. The clinical significance lies in being aware of this rare entity in the stomach and distinguishing it from other benign and malignant gastric neoplasms that may be in the differential diagnosis. We herein discuss the clinical presentation, radiologic and histopathologic features, ancillary studies, differential diagnosis, and treatment and prognosis of this rare entity.

Context.— Cellular spindled histiocytic pseudotumor (CSHPT) is an exuberant, dense histiocytic proliferation seen in the setting of mammary fat necrosis. CSHPT has a broad histologic differential diagnosis, including benign, malignant, and inflammatory etiologies. Objectives.— To highlight the most important histologic and immunohistochemical findings of CSHPT and provide comparisons to entities within the broad differential diagnosis. Data Sources.— Recently published literature regarding CSHPT and other diagnostic considerations. Conclusions.— CSHPT is a benign histiocytic proliferation with a broad differential diagnosis, for which comprehensive ancillary studies may be required to exclude malignant and infectious entities.

Benign spindle cell lesions of the breast include neoplastic and reactive entities that are diagnostically challenging given their rarity and similar histomorphology. Accurate diagnosis on percutaneous core biopsy within this category is essential as some lesions require excision and surveillance, whereas others may be observed. We present three cases of rare benign spindle cell lesions of the breast that reflect the diversity of this group: solitary fibrous tumour, nodular pseudoangiomatous stromal hyperplasia and nodular fasciitis. Through these cases, we discuss the associated differential diagnosis and demonstrate how emerging ancillary studies can be integrated into a diagnostic approach. We highlight distinctive clinical and histopathological features and summarise recent updates to the clinical management of these lesions. An organised approach to the broad differential of spindle cell lesions is essential for appropriate diagnosis and treatment.

Spindle cell variant of Rhabdomyosarcoma is a rare malignant tumor in adults but even more so in tongue. We report a case of a 17 year old boy who presented with a polypoidal swelling on the tip of the tongue. The mass was excised and the specimen was sent to the Histopathology Department of Armed Forces Institute of Pathology for Histomorphological diagnosis. The histological evaluation showed a malignant spindle cell tumor. On the basis of morphological features and immunohistochemistry findings a final diagnosis of Rhabdomyosarcoma, Spindle cell variant was made.

Castleman's disease is a benign lymphoid neoplasm first reported as hyperplasia of mediastinal lymph nodes. Some authors referred to the lesions as isolated tumors, described as a variant of Hodgkin's disease with a possibility of a malignant potential and others proposed that the lymphoid masses were of a hamartomatous nature. Three histologic variants and two clinical types of the disease have been described. The disease may occur in almost any area in which lymph nodes are normally found. The most common locations are thorax (63%), abdomen (11%) and axilla (4%). We report two separate histologic types of Castleman's disease which were rare in the literature, mimicking sigmoid colon tumor and Hodgkin lymphoma. The diagnostic and therapeutic aspects of this rare entity is discussed.

Polycystic (dysgenetic) disease of the salivary glands is a rare entity that has only recently been described in the literature. The disease is more commonly seen in females and majority of the cases have presented as bilateral parotid gland swellings. This case presenting in a 21-year-old male is the first of this unusual entity involving solely the minor salivary gland on the lower lip. This case report highlights the importance for the clinician to be aware of this differential diagnosis, when treating an innocuous lesion like a mucocele.

Abstract In this report, we document the histologic and clinical features of a previously undefined spindle cell variant of ameloblastoma that eventually behaved in a malignant fashion during a protracted course. The predominant histologic pattern was a well-differentiated, cellular, spindled epithelial proliferation arising in the maxilla of a 14-year-old African American girl. Over 19 years, the patient experienced numerous local recurrences, metastases to distant bones after 15 years, and finally bulky local recurrence with intracranial extension resulting in death. This ameloblastic malignancy histologically simulates a low-grade true sarcoma or an ameloblastic sarcoma, but differs in that the extensive spindle cell proliferation is epithelial, characterized by strong cytokeratin immunoreactivity and negative vimentin staining.
