Cutaneous myxoma is an uncommon soft tissue lesion associated with Carney Complex (CNC). In this case report, we present a 33-year-old male with a soft tissue mass that was found to be a cutaneous myxoma after excision. It was initially thought to be a cyst during a visit to a nearby emergency department, at which point, the patient was referred to our surgical clinic for further management. He hoped to have the mass removed as he was concerned about cosmesis and the possibility of neoplasia. .....

Bladder cancer is the most common malignancy of the urinary tract. Calcitriol [1,25(OH)2 vitamin D3] has anticancer effects mediated through binding to vitamin D receptor (VDR). The expression of VDR is present in many normal and cancer tissues. But there is little information about its expression in urinary bladder carcinoma. This study aimed to analyze VDR immunohistochemical expression in 74 Egyptian patients with urinary bladder carcinoma and to evaluate its association with different clinic...

The Pfizer and Moderna COVID-19 vaccines are composed of lipid nanoparticles (LNP) containing a modified messenger RNA (mRNA) that encodes for the Spike S protein. The LNP transfection likely involves particle engulfment by the host immune cells due to their resemblance to apoptotic bodies, vesicles with externalized phosphatidylserine (ePS). As the LNPs are decorated with PS-like ionizable phospholipids, including 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC), they encourage human phagocyte...

Colorectal carcinoids were low-grade tumors especially those of small polypoid tumors (< 1.0 cm) with CgA-negative staining while larger tumors (> 2.0 cm) infiltrating through wall were more aggressive with often CgA positive staining. CgA positive carcinoids of duodenum, small intestine and colorectum of larger th...

Metastases to the foot bones are uncommon and they mimic inflammatory conditions. Acrometastases may be the first manifestation of an unknown primary malignant disease. We report a case in which the first sign of lung adenocarcinoma was a pathological fracture due to metastasis to a proximal toe phalanx. A 68-year-old man was evaluated for pain in his fifth toe of the left foot after a trauma. Biopsy and immunohistochemistry reactions confirmed the metastatic lesion. Unfavorable clinical course ...

Peripheral T cell lymphoma (TCL) is relatively uncommon and may involve lymph node, skin and extra-nodal non-cutaneous organs. Nodal TCL often presents as systemic disease with unfavorable outcomes. Extra-nodal non-cutaneous TCL, however, may remain as localized disease and be treated differently with favorable prognosis. This study revealed the common peripheral blood findings and clinical follow ups in patients with extra-nodal non-cutaneous mature TCL. There were 9 patients, 5 males and 4 fem...

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease characterized by neurocognitive decline and abnormal neuronal and glial deposition of hyperphosphorylated-tau in a pattern distinct from other tauopathies. These changes are hypothesized to occur following repeated mild traumatic brain injury. We report a case of CTE-like neuropathological changes, and features of motor neuron disease in a patient without history of either head trauma or participation in activities associated ...

Dedifferentiation of leiomyosarcoma is a rare phenomenon that associates pleomorphic histology and loss of smooth muscle differentiation. Although the leiomyosarcoma is well known sarcoma in the uterus, and the dedifferentiated leiomyosarcoma is well recognized in the soft parts, there are only a few reports of dedifferentiation of leiomyosarcoma in the uterus. Herein we present a case of dedifferentiated uterine leiomyosarcoma and discuss its relation to the undifferentiated uterine sarcoma....

Kernicterus is a severe manifestation of neonatal unconjugated hyperbilirubinemia. We investigated the neuro-glia-vascular alterations in autopsy material from three infants with kernicterus. Histological and immunohistochemical studies were performed in the cerebellum, hippocampus and basal ganglia, the most vulnerable brain regions to bilirubin-induced neurotoxicity. The data obtained were compared with the relatively spared temporal cortex, as well as with three aged-matched controls with no ...

During the last ten years studies on the role of cholesterol in the development and progression of cancer process and observations of severe hypocholesterolemia in patients with solid tumours and hematologic malignancies have been extended. Th cancer cell incorporates cholesterol with avidity and reduces its serum level. In normal cells, cholesterol binds sphingomyelin with very long-chained saturated fatty acids to form membrane lipid raft that acts as platform for proteins and receptors....
