Malignant transformation (MT) arising from the mature cystic teratoma (MCT) is a rare occurrence, comprising about 1% – 3% in all documented MCTs. Majority of MT cases are squamous cell carcinoma, followed by adenocarcinoma, then neuroendocrine neoplasm. Bilateral ovarian MCT with both MTs of different types is extremely rare. This is the first documented case in the Philippines....

Primary central nervous system lymphoma (PCNSL) was an uncommon variant of extranodal non-Hodgkin lymphoma. Contrast-enhanced MRI imaging was the method of choice for detecting PCNSL. The purpose was to describe the MRI and pathologic features of PCNSL and to determine whether there was a correlation between it....

Myoepithelial carcinoma, also known as malignant myoepithelioma, is mainly encountered in the salivary glands and, at a lower incidence, in the sweat glands (skin), breast, soft tissue, bone and very rarely in the lung. Pulmonary myoepithelial carcinoma was first described by Higashiyama et al. in 1998, and to the best of our knowledge, only 15 cases have been reported in the English literature so far....

Hanging is the most popular method of suicide. Several different mechanisms are explained how death after hanging occurs, including direct injury to the thyroid gland. This study aimed to determine the possibility of death associated with acute excess levels of thyroid hormones in the deceased body by hanging and to find the correlation of thyroid hormone levels and various factors associated with that body. ...

Adrenal myelolipomas are rare benign tumours of the adrenal gland which are usually asymptomatic in nature. The reported incidence of this tumour is 0.08 to 0.2% from all primary tumours of the adrenal glands. With the advent of imaging techniques such as ultrasonography, computed tomography and magnetic resonance imaging almost 15%...

Rhinosporidiosis is a rare and chronic infestation caused by fungus Rhinosporidium seeberi, seen in India and Sri Lanka and is hyperendemic in southern parts of Tamil Nadu. It predominantly affects mucus membrane of nose and nasopharynx causing polypoidal growth....

Human leucocyte antigen B27 (HLA-B27) is a major histocompatibility complex class 1 molecule that is strongly associated with ankylosing spondylitis. The polymerase chain reaction with sequence specific primers (PCR-SSP) is currently used for the discrimination of HLA-B27 allele types resulting from single base substitutions....

Neurological manifestation of thrombotic microangiopathy (TMA) after renal transplantation is rare and difficult to be distinguished from other conditions. A 51-year-old female with ESRD of unknown etiology received deceased donor kidney transplantation from a 57-year-old donor....

Thymoma is the most common mediastinal tumor in adulthood. By definition, it is a thymic epithelial neoplasm that displays at least some characteristics of normal thymus. Microscopically it comprises an admixture of thymic epithelial cells and immature T lymphocytes in various proportions and demonstrates marked intratumoral heterogeneity...

The number of metastatic lymph nodes to the total number of dissected axillary lymph nodes (lymph node ratio: LNR) is described as an independent prognostic factor in breast cancer patients, beside the traditional account of the number of axillary lymph node metastasis (pN stage). We investigated the correlation between LNR and prognosis among Thai...
