RESUMEN
Hereditary hemorrhagic telangiectasia (HHT) is a disorder characterized by telangiectasias and arteriovenous malformations. We present a case report of a 74-year-old man diagnosed with HHT having a favorable response to a somatostatin analogue for treatment. This patient had been suffering from chronic anemia from recurrent gastrointestinal bleeding, requiring oral/intravenous iron replacement, frequent endoscopic ablations, and blood transfusions. Due to insufficient treatment, he was started on subcutaneous octreotide, with significant improvement as evidenced by a steady increase in the hemoglobin level, decreased endoscopic interventions, and decreased blood transfusions, making this the first case of HHT successfully treated with octreotide.
RESUMEN
Endosalpingiosis rarely affects the appendix but can be mistaken for acute appendicitis or appendiceal tumors. The medical literature regarding appendiceal endosalpingiosis is sparse; consisting of only four case reports which are primarily focused on the histopathology but provide little radiologic correlation. Endosalpingiosis is a rare condition characterized by the presence of benign fallopian tubal-like glandular epithelium derived from Mullerian ducts, usually affecting the serosal surfaces of the pelvis and peritoneum. It is histologically differentiated from endometriosis as endosalpingiosis lacks endometrial stroma. Endosalpingiosis tends to affect older women and has been associated with ovarian serous tumors of low malignant potential. After a retrospective review of a pathology database, we present pathologically proven cases of appendiceal endosalpingiosis with correlative imaging. We discuss the clinical presentation, illustrate the CT and MRI appearance, histologic characteristics, and review the current medical literature of appendiceal endosalpingiosis.

We investigated the role of suppressor of cytokine signaling-1 (SOCS1) and SOCS3 molecules in lymph nodes from tuberculous lymphadenitis patients (LNTB). Fewer T cells were noted in LNTB cases, which also had raised chemokine (C-X-C motif) receptor 3 (CXCR3) levels. In addition, we observed a positive correlation between CXCR3 and SOCS1 expression. Our data suggest that upregulation of SOCS1 molecules may contribute to the dissemination of Mycobacterium tuberculosis from granulomas.

Dermatofibrosarcoma protuberans (DFSP) is a relatively intermediate to low grade malignant tumour with high proclivity for local recurrence if excised inadequately. It is a locally aggressive tumour and despite sharing some histological features with fibrohistiocytic tumours, it tends to grow in a more infiltrative manner. We are reporting this rare tumour in a 30-year-old woman where the diagnosis of DFSP was confirmed histologically and by positive immunomarkers at immunohistochemistry.
