Mucoepidermoid carcinoma (MEC) with a predominant spindle cell composition occurring in the palatine tonsil is exceedingly rare. We present a case of a 17-year-old boy with an uncommon spindle cell variant of MEC arising in the palatine tonsil. Histologically, the tumor showed a solid, noncystic architecture and was composed of a predominant population of bland spindle to fusiform cells arranged in organoid nests with interspersed goblet cells and focal areas of ductular structures. Reverse transcriptase polymerase chain reaction and fluorescence in situ hybridization (FISH) revealed the presence of a t(11;19) CRTC1-MAML2 gene fusion in this rare variant of MEC...

Sclerosing stromal tumors of the ovary are very rare. We report the case of a 29-year-old pregnant woman who presented with a history of preterm labor and gestational hypertension. A huge mass measuring 30 cm in greatest dimension was recognized on the right ovary during cesarean section. Signet ring cell infiltration was seen during intraoperative frozen section consultation. She underwent a right salpingo-oophorectomy, and the permanent diagnosis was sclerosing stromal tumor infiltrated by signet ring cells...

Here, we report an unusual case of sarcomatoid carcinoma mimicking extraskeletal osteosarcoma that manifested as recurrent rectal cancer. Five years earlier, a 76-year-old male patient had undergone neoadjuvant chemoradiotherapy followed by a laparoscopic low anterior resection due to adenocarcinoma of the rectum. He was admitted because of pain in the anus and left hip. He underwent abdominal computed tomography that revealed a newly developed left perirectal mass with gluteus maximus invasion measuring up to 8 cm, and therefore, an abdominoperineal resection was performed...

Giant bullous emphysema with placental transmogrification is an extremely rare entity, with 30 previously reported cases. Of these reported cases, it is typically identified with varied clinical and radiological impressions, presents in young adulthood to elderly, is always unilateral, and usually involves just one lobe. Despite the unknown pathogenesis, this diagnosis carries an excellent prognosis and is curative with complete resection. The pulmonary placental transmogrification is histologically indistinguishable from placental origin...

BACKGROUND: Acute kidney injury (AKI) often manifests in patients with liver disease because of a prerenal cause and presents as acute tubular necrosis or hepatorenal syndrome. Distinguishing between these entities is important for prognosis and treatment. Some patients may develop AKI related to their underlying liver disease: for example, membranoproliferative glomerulonephritis or IgA nephropathy. Bile cast nephropathy is an often ignored differential diagnosis of AKI in the setting of obstructive jaundice...

IgG4-related sclerosing disease of the breast is a rare entity with 10 reports in the literature. We report the first case in a male patient. A 48-year-old male presented with 4-week history of palpable right upper outer quadrant breast mass associated with skin puckering. He reported a family history of breast cancer in his aunt. Ultrasound and mammography showed a spiculated 2.5-cm mass associated with skin retraction with extension to the pectoralis muscle. Ultrasound-guided core biopsy was performed. The findings were interpreted as acute and chronic inflammatory process...

Granular cell tumor (GCT) rarely involves the central nervous system, and fewer than 100 cases have been reported in English literatures. We herein report a case of a 36-year-old Chinese man with GCT of the neurohypophysis. Magnetic resonance imaging showed one mass located in the hypophysis with heterogeneous contrast enhancement. Pathological examination showed a neoplasm comprising densely packed polygonal cells of ample cytoplasm with abundant eosinophilic granules inside. The nuclei were small with inconspicuous nucleoli and yet without any mitoses...

Primary central nervous system T-cell lymphoma (PCNSTCL) is rare, accounting for 2% of CNS lymphomas. We report the first case of PCNSTCL with aberrant expression of CD20 and CD79a in an 81-year-old man with a left periventricular brain mass. A biopsy revealed dense lymphoid infiltrate consisting of medium-sized cells in a background of gliosis and many histiocytes. The lymphoid cells were positive for CD2, CD3, CD7, CD8, T-cell intracellular antigen-1, granzyme B, CD20, and CD79a and negative for CD4, CD5, PAX-5, OCT-2, BOB-1, human herpes virus-8, and Epstein-Barr virus-encoded small RNAs...

Posttraumatic fibro-osseous lesion (PTFOL) is a rare lesion that typically affects the ribs and is probably a posttraumatic reactive process. Because PTFOL is often misdiagnosed as fibrous dysplasia, osteoid osteoma, benign fibrous histiocytoma or rib metastases, chest wall resection, leading to a significant morbidity, is the main treatment modality. We report the case of a 30-year-old male patient with no history of previous trauma presenting with chest pain. Computed tomography scan showed an eighth left rib well-defined ovoid and hypodense lesion with circumferential sclerotic margin and no cortical breakthrough...

Parvovirus B19 infection is undiagnosed in recipients undergoing solid organ transplantation. It is usually responsible for unexplained acute and chronic red blood cell aplasia that does not respond to erythropoietin therapy. Cases of parvovirus B19 infection associated with pancytopenia, solid organ dysfunction, and allograft rejection have been described in the literature. The deterioration of the immune system as a result of severe immunotherapy favors the reactivation of a previous infection or the acquisition of a new one...

Ependymomas are glial neoplasms with rare cases exhibiting neuronal differentiation. We describe a case of spinal anaplastic ependymoma with ganglionic differentiation in a 28-year-old woman. The ganglionic component was labeled by synaptophysin, whereas the rest of the tumor showed features of an anaplastic ependymoma. Stem cell marker MELK was noted to stain both the neoplastic ependymal and ganglionic components, possibly suggesting a stem cell/progenitor origin for the tumor with subsequent divergent differentiation...

Syringoid eccrine carcinoma is a rare malignant adnexal tumor that typically presents in the head and neck region. Involvement of the extremities is uncommon, with only a few cases reported in the literature. Here, we report our experience with a rare case of syringoid eccrine carcinoma occurring on the plantar surface of the right foot in a 47-year-old African American woman. Histologically, incisional biopsy revealed a tumor consisting of tubulocystic structures lined by basaloid cells with an infiltrative growth pattern, extending from the reticular dermis to the deep biopsy margin...

INTRODUCTION: Mixed adenoneuroendocrine carcinoma (MANEC) has recently been defined by the World Health Organization in 2010. These are rare tumors and MANECs of ampullary region are even rarer. Only 19 cases have been reported in literature. We present 3 cases; the largest series, second case of amphicrine tumor and first case associated with chronic pancreatitis. METHODS: Retrospective review of 3 patients who were diagnosed to have ampullary MANEC. RESULTS: All 3 patients were diagnosed preoperatively as neuroendocrine carcinoma and underwent margin negative pancreaticoduodenectomy...

Histoplasmosis is an invasive mycosis caused by inhalation of the spores of dimorphic fungi Histoplasma capsulatum. The disease manifests in the lung as acute or chronic pulmonary histoplasmosis and in severe cases gets disseminated in multiple organs like skin, adrenal gland, central nervous system, lymph node, liver, spleen, bone marrow, and gastrointestinal tract. It occurs most commonly in immunodeficient patients like HIV-positive patients and transplant recipients, while immunocompetent hosts are affected rarely...

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft-tissue tumors. They can occur in patients with neurofibromatosis type-1 (NF-1) or as sporadic tumors. Only 10% of MPNSTs are radiation induced. Divergent differentiation in MPNSTs can occur in 15% of cases and may include cartilage, bone, skeletal muscle, blood vessels, and very rarely well-formed glands, the latter typically described in NF-1-associated MPNSTs. We report an exceedingly rare case of radiation induced glandular MPNST arising in a neurofibroma of the femoral nerve in a patient previously irradiated for endometrial carcinoma...

The histological diagnosis of malignant peripheral nerve sheath tumor (MPNST) is challenging because of the wide morphological spectrum and suboptimal performance of conventional immunohistochemical markers. MPNST arising primarily in the bone is exceptional, and its definitive diagnosis, particularly out of the neurofibromatosis type 1 (NF1) context, is even more problematic. Recurrent inactivation of EED or SUZ12 in a majority of MPNSTs results in a complete loss of trimethylated histone H3 at lysine 27 (H3K27me3) immunoreactivity, making it a highly specific biomarker of MPNSTs...
