The purpose of this retrospective chart review study was to review the nature and clinical course of benign and malignant submandibular gland tumors at 2 major university-affiliated tertiary medical centers. All patients who underwent submandibular salivary gland excision between 1990 and 2010 were included. Clinical and disease-related data were collected from the medical charts. One hundred ninety-three patients were identified, of whom 108 (56%) had non-neoplastic disorders (sialolithiasis and sialadenitis)...

We demonstrated an extremely unusual case of an 83-year-old male's sudden death secondary to characteristic myocardial necrosis and fibrosis with calcification and multinucleated giant cells infiltration, possibly due to sepsis and Stage IV pulmonary pleomorphic carcinoma-induced cachexia after postmortem study. We propose that this calcifying giant cell cardiomyopathy (CGC) would be a new entity especially from the pathological viewpoints and should be considered in the classification of noninfectious myocarditis...

Salivary adenoid cystic carcinoma (AdCC) is a common head and neck cancer with the propensity for local spread and distant metastasis. In our previous study, elevated expression of Anterior gradient 2 (AGR2) was detected in head and neck squamous cell carcinoma (HNSCC), associated with epithelial-mesenchymal transition (EMT) and cancer stemness. However, to date, the expression and function of AGR2 in AdCC has yet to be elucidated. In the present study, human AdCC tissue microarrays including 18 cases of normal salivary gland (NSG), 12 cases of pleomorphic adenoma (PMA) and 72 cases of AdCC were employed for immunohistochemical staining analysis...

BCAP31, encoded by BCAP31, is involved in the export of transmembrane proteins from the endoplasmic reticulum. Pathogenic variants in BCAP31 results in global developmental delay, dystonia, deafness and dysmorphic features in males, called deafness, dystonia, and cerebral hypomyelination (DDCH) syndrome. We report a new patient with BCAP3-associated encephalopathy, DDCH syndrome, sensorineural hearing loss, generalized dystonia, and choreoathetosis. This 3.5-year-old boy had microcephaly and failure to thrive within the first 3 months of life...

We report a case of a 56-year-old male patient with a life-threatening left common femoral artery bleeding due to tumor erosion. The patient had a history of advanced high-grade pleomorphic leiomyosarcoma of the left groin with pulmonary metastasis. Clinical examination revealed a massive tumor bulking at the left groin with necrosis and phleb- and lymphedema. Given the circumstances, open surgery was not possible. Thus, it was decided to treat the patient with an endovascular procedure. The postprocedural course was uneventful, the patient received blood product and was hemodynamically stable...

Inflammatory myofibroblastic tumors (IMTs) are uncommon breast lesions that consist of spindle cells accompanied by plasma cell-rich inflammatory infiltration, which may mimic breast cancer clinico-radiologically. A woman aged 38 years with a breast mass was referred to our general surgery clinic. The physical examination revealed a mass with irregular borders in the upper outer quadrant of the left breast. In mammography, the lesion was 15 mm in diameter with a spheric form and high density. Ultrasonographically, the mass was solid, heterogeneous, and hypoechoic with posterior enhancement...

We describe an interesting case of pleomorphic fibroma of the subungual region in a middle aged woman who presented with a recurrence of thickening, lateral ridging, and a midline split of the right third fingernail, 20 years after initial excision. Histology of the specimen demonstrated hyperchromatic stellate cells within the superficial corneum, which were CD34 positive, consistent with a pleomorphic fibroma. Pleomorphic fibroma is a rare mesenchymal neoplasm characterized by atypical spindled cells amidst a collagenous stroma...

Cutaneous mastocytosis is defined by the presence of mast cells within the skin in the absence of other criteria for the diagnosis of systemic mastocytosis. Mast cells are characterized by an abundant granular cytoplasm and a round to oval or spindle-shaped nuclei. The presence of mast cells with bilobed and multilobed nuclei in cutaneous mastocytosis is a rare phenomenon and has been rarely reported in the literature. To our knowledge, there are only 4 reported cases of cutaneous mastocytosis with atypical mast cells...

Angiosarcomas are highly aggressive malignancies of vascular origin and are very rarely found in children. We report a case of a 13-year-old girl with a history of abdominal pain and increased abdominal girth. Radiologic imaging showed significant ascites and large pelvic masses involving bilateral adnexa with abdominal spread. Microscopic examination of a biopsy revealed pleomorphic epithelioid and spindle cells with brisk mitotic activity, intracytoplasmic vacuoles, vascular channels, and large areas of hemorrhage and necrosis...

OBJECTIVE: To investigate the clinical significance of cell blocks obtained by ultrasound-guided fine needle aspiration in diagnosing parotid gland masses. METHODS: Cell blocks were made in 285 parotid gland masses by ultrasound-guided fine needle aspiration. Diagnosis was conducted using the cell blocks. Non-tumor masses were subjected to conservative treatment, and cysts and tumors were treated with surgery. The cell block sections from masses with the diagnosis of adenoid cystic carcinoma (ACC) and pleomorphic adenoma (PA) were applied to the detection of immunocytochemical staining for the stem cell factor receptor CD117...

Myoepitheliomas of soft tissue are rare tumors with variable morphologic, immunohistochemical and molecular profiles and therefore are diagnostically challenging for pathologists. We report a case in a 60-year-old male with a painless slowly growing 3cm mass on left medial forefoot. Core biopsy of the mass showed a neoplastic proliferation of plasmacytoid tumor cells, consistent with myoepithelioma of soft tissue. Immunohistochemical stains demonstrated positivity of the tumor cells for cytokeratin AE1/AE3, CK18, S-100 protein and myosin heavy chain (SMMS-1), supporting the diagnosis...

A 40-year-old woman was referred to our hospital with abnormal findings on chest X-ray. Her medical history was remarkable in that she had presented with a pleomorphic adenoma in the right parotid gland treated by surgical removal approximately 12 years previously. Chest computed tomography showed well-defined non-calcified nodules of the bilateral lobes, so she underwent segmentectomy of the right upper lobe and middle lobe. The histopathological diagnosis was metastasizing pleomorphic adenoma of the lung, a rare entity...

BACKGROUND: Imaging and histology of clear-cell ependymoma and cerebellum-based hemangioblastoma are similar; distinguishing between them is a diagnostic challenge. CASE PRESENTATION: A 62-year-old Chinese woman presented with an intermittent headache of 8 years' duration. Computed tomography and magnetic resonance imaging revealed a mass in the cerebellum. Neurological imaging suggested hemangioblastoma (HB). Histologically, the tumor included cellular and paucicellular areas, in which cells were arranged in nests or diffusely distributed; and a highly vascular area, in which tumor cells were arranged in clusters and separated by capillaries...

We describe a distinctive renal tumor, a myolipoosteoma (MLO), in an 11-year-old boy who presented with a 6-month history of slight right flank intermittent pain. A gross examination revealed a well-defined, 5.5 cm mass with bone-like consistency. The lesion histologically featured an admixture of mature adipose tissue, spindle cells, and bony components. No atypia, mitotic activity, or pleomorphisms were observed in the tumor. The spindle cells were smooth muscle actin (SMA) and desmin positive but HMB45 and Melan-A negative, indicating that they were of a muscular nature and differed from that of angiomyolipoma (AML)...

Breast cancers that present with mucin include mucinous carcinoma and carcinoma with signet ring cell differentiation. The former shows extracellular mucin and the latter shows abundant intracellular mucin. Here, we report a case of breast cancer showing both extracellular mucin and extensive signet ring cell differentiation due to abundant intracellular mucin. Unlike mucinous carcinoma, this case had the features of high-grade nuclear pleomorphism, high mitotic index, estrogen receptor negativity, progesterone receptor negativity, human epidermal growth factor receptor-2 positivity, and ductal type with positivity for E-cadherin...

An unusual case of a polypoid, malignant gastric tumor in a 62-year man is presented. Endoscopy and subsequent polypectomy revealed an 8.5 x 6.5 x 4.5cm lesion in the body of the stomach. Microscopy showed surface dysplasia with an invasive adenocarcinoma displaying prominent tubulopapillary areas composed of large vacuolated cells, pleomorphic nuclei and occasional cytoplasmic hyaline globules. This component then blended with tubular structures lined by more primitive appearing vacuolated cells embedded within a stroma made up of cellular primitive, high-grade blastema-like areas and, less cellular more pleomorphic foci with spindle and several bizarre, large cells...

A solitary fibrous tumour (SFT) is a rare mesenchymal tumour that frequently originates in the mesothelium-covered surfaces, such as the pleura and peritoneum. It may develop in various body parts, including the head and neck. These tumours may arise in several different patterns, which results in difficulties in diagnosing them. This case is a solitary tumour developing from the palatine tonsil in a 17-year-old male patient; it is the second case in the literature. The tumour has the histopathological characteristics of a patternless pattern, a slight pleomorphism, and a composition of hypercellular and hypocellular sites...

Interdigitating dendritic cell sarcoma (IDS) is a rare form of hematologic malignancy associated with an aggressive clinical course. Only 4 prior cases have been described as originating in the skin. We encountered two male patients ages 47 and 61years of age who presented with solitary cutaneous neoplasms diagnosed as IDS. Histologic exam showed a coalescing nested and multinodular proliferation of large pleomorphic epithelioid cells. In one case an initial diagnosis of melanoma was rendered. A recurrence 8months later was then interpreted as a primary cutaneous IDS...

BACKGROUND: Pre-Descemet corneal dystrophy (PDCD) is characterized by the presence of numerous, tiny, polymorphic opacities immediately anterior to Descemet membrane, which is a rare form of corneal stromal dystrophy and hard to be diagnosed. In vivo confocal microscopy (IVCM) is a useful tool to examine the minimal lesions of the cornea at the cellular level. In this article, we report a rare case of PDCD associated with X-linked ichthyosis and evaluate IVCM findings. CASE PRESENTATION: We present a 34-year-old male Chinese patient with PDCD associated with X-linked ichthyosis...
