Abstract Background To our knowledge, we report the first case of an aneurysmal benign fibrous histiocytoma occurring in the anal canal. Methods Clinical, histological, radiological and surgical data pertaining to this patient were analysed. Additionally, a literature review on aneurysmal benign fibrous histiocytoma was conducted. Results We describe a 48-year-old Caucasian male presenting with a 2-week history of a painful anus, fresh rectal bleeding and tenesmus. Digital rectal examination identified a tender firm mass in the anal verge. Magnetic resonance imaging revealed high signal in the anal canal. Flexible sigmoidoscopy revealed an ulcerated 3-cm indurated lesion at the four o’clock position. Biopsies taken of the mass confirmed the diagnosis of an aneurysmal benign fibrous histiocytoma (BFH). Following a discussion in the colorectal multi-disciplinary team, the patient was counselled for an excision of the lesion. Diathermy dissection was performed to completely excise the tumour with a margin involving the fibres of the anal sphincter. The patient made a full recovery and had no residual symptoms. Histology of the excised specimen confirmed clear margins of the BFH. Conclusions This paper aims to highlight a rare differential diagnosis for an anal mass. An aneurysmal BFH most often presents as a painless mass within the dermis and subcutaneous tissue. As such, this case presents a diagnostic challenge to both colorectal surgeon and histopathologist due to its low incidence and unusual location. We further present the clinical and radiographic evidence to confirm the diagnosis. Additionally, we discuss the literature pertaining to this condition and its optimal management.

Abstract A number of fibrous lesions involving bone display almost identical histologic appearances yet may represent either reactive or neoplastic conditions, resulting in a confusing nomenclature and possible diagnostic confusion. We report the case of a young man with no significant previous medical history who presented with a painful lesion in the left shoulder, which consisted almost entirely of xanthomatous material. We discuss the possible differential diagnosis of this lesion and why benign fibrous histiocytoma is the preferred terminology for this lesion. To our knowledge, this is the first reported case of a benign fibrous histiocytoma involving the acromion in an adult.

Benign Fibrous Histiocytoma

Benign fibrous histiocytoma is a rare benign primary skeletal tumor that occurs frequently in the long bones and the pelvis. The calcaneus is an unusual location for benign fibrous histiocytoma. We did not identify any case of benign fibrous histiocytoma involving the calcaneus in the relevant literature. We describe a 22-year-old male patient with benign fibrous histiocytoma involving the calcaneus treated with curettage and bone grafting. At the final follow-up visit, 1 year after surgery, the patient was free of pain and walking unaided. We discuss the differential diagnosis of cystic lesions of the calcaneus.

<p>The fibrous histiocytoma is a soft tissue neoplasm that affects the dermis and the subcutaneous tissue, rarely is found in the oral cavity and perioral regions, and is originated from the proliferation of fibroblasts and histiocytes. The objective of this paper is to report a case of Benign Fibrous Histiocytoma in a 30-year-old male patient, complaining of a painless nodule in the tongue for about six months. With the clinical diagnostic hypotheses of Fibrous Hyperplasia or Traumatic Neuroma an excisional biopsy was performed. The histopathological examination revealed a non-encapsulated proliferation of spindle cells with some giant multinucleated cells in the periphery of the lesion.  Immunohistochemical reactions were performed, staining only for vimentin in the spindle cells and for CD68 in the multinucleated giant cells. According to these characteristics, the final diagnosis was Benign Fibrous Histiocytoma. The correct diagnosis of spindle shaped cell neoplasia must be performed with the aid of histopathological analysis and immunohistochemistry, mainly because the morphological similarities with other benign and malignant lesions. </p>

Abstract A case of primary intracerebral plasma cell granuloma without meningeal attachment is presented. Histologically, the lesion showed two different patterns. At the center, it displayed the features of a benign fibrous histiocytoma. At the periphery, a mixture of polyclonal plasma cells, lymphocytes, and “epithelial-like”cells was observed. Electron microscopy and immunocytochemistry confirmed the histiocytic nature of the “epithelial-like cells.” The differential diagnosis and histogenesis of such a lesion are discussed.

Abstract We report the first case of cerebral Fonsecaea monophora infection in a German woman without immunodeficiency or travel history. F. monophora infection is a rare differential diagnosis of cerebral tumors; it was previously considered a tropical fungus. This case adds to the scarce reports in nontropical regions.
