Mesotheliomas are a rare malignancy of the serosal membrane. Mainly it affects the pleural surfaces followed by the second most common location, "peritoneum." The disease follows an aggressive pattern of spread, and by the time the diagnosis is established, the condition significantly spreads to distant locations.

Depending on the host's immunological and respiratory systems, can induce infectious and allergic diseases. Most of the spread occurs in immunocompromised people, whereas aggressive disorder in immunocompetent patients is unusual. We report the case of a 19-year-old female who had shortness of breath, right-sided chest discomfort, and intermittent hemoptysis for six months before being diagnosed with pulmonary aspergilloma.

Colorectal cancer (CRC) is more prevalent in south-central Asian countries, particularly the Afghan population. Screening for CRC in the Afghan population has always been challenging, primarily due to the tribal and social cultures, lack of facilities, and lack of education. The United States (US) will soon face a significantly massive influx of Afghan refugees.

Introduction: Parathyroid carcinoma (PC) is an extremely rare entity, with a frequency of 0.005% of all malignancies. Most data related to this rare disease are limited to case series and a few database studies.

Background: Primary peritoneal mesothelioma (PPM) is a rare and aggressive tumor arising from the visceral and parietal peritoneum. The diagnosis and treatment of PPM are often delayed because of non-specific clinical presentation, and the prognosis is worse. The current study investigated the demographic, clinical, and pathological factors affecting patient prognosis and survival in PPM.

Introduction: Celiac disease (CD) is an immune-mediated disease caused by ingesting gluten-containing foods and is characterized mainly by malabsorptive diarrhea. Furthermore, distinguishing between mild disease and asymptomatic individuals is critical and necessitates a high level of clinical suspicion. Short stature, delayed puberty, bone abnormalities, neurological problems, and intestinal cancer can all be consequences of a delayed diagnosis.

The prognosis of cutaneous melanoma (CM) is based on the histological characteristics of the primary tumor, such as Breslow depth, ulceration, and mitotic rate. The lymph node ratio (LNR) is the ratio of the involved lymph nodes (LNs) divided by the total number of LNs removed during regional LN dissection. LNR is a prognostic factor for many solid tumors; however, controversies exist regarding CM.

Introduction Klatskin tumors (KTs) occur at the confluence of the right and left extrahepatic ducts and are classified based on their anatomical and histological codes in the International Classification of Diseases for Oncology (ICD-O). The second edition of the ICD-O (ICD-O-2) allocated a distinctive histological code to KT, which also included intrahepatic cholangiocarcinoma (CC). This unclear coding may result in ambiguous reporting of the demographic and clinical features of KT.

Background: Uterine cancer (UC) is one of the leading gynecologic neoplastic disorders in the United States (US), of which over 80% are endometrioid adenocarcinomas (EA). In contrast to EA, carcinosarcoma (CS) of the uterus is a sporadic and highly malignant tumor, phylogenetically containing both epithelial and mesenchymal histologic elements. This study sought to analyze demographic, pathological retrospectively, and survival characteristics of a large cohort of CS patients compared to EA patients to identify prognostic factors and treatment approaches that may improve the current clinical management of CS patients.

Ectopic thyroid tissue (ETT), though an uncommon finding, is prone to be clustered along the midline in the neck and rarely it shows up as a lateral neck mass. Whenever the ETT is discovered in unusual places, the possibility of malignancy is higher, and rarely a benign variant. We present a 71-year-old female with a past history of hypertension, hypercholesteremia, and thyroid nodules presented to the physician's office complaining of an unusual swelling in the right side of a neck.

Introduction Rectal cancer remains a leading cause of cancer morbidity and mortality in the United States. Currently, total mesorectal excision (TME) is the standard therapy for patients with T2N0 (stage IB) rectal cancer. Whether adjuvant radiation therapy provides a survival benefit to these patients or exposes them to unnecessary toxicity remains controversial and unproven to date.

Introduction: Flank incisions may be associated with incisional flank hernias, which may progress to incarceration and strangulation. Compromised integrity of the abdominal and intercostal musculature due to previous surgery may be associated with herniation of abdominal contents into the intercostal space. There have been six previously reported cases of herniation into the intercostal space after a flank incision for a surgical procedure.

44-year-old female with massive chronic tubo-ovarian abscess complicated by hepatic portal venous gas (HPVG). She presented to the emergency department of our hospital with a diffusely tender abdomen and 2 weeks history of frequent non-bloody loose stools. She had a relevant past medical history of poorly controlled type 1 diabetes mellitus and hypertension.

Recruitment of more underrepresented minority students (black, Hispanic and native American) to increase racial diversity in the physician workforce is on the agenda for medical schools around the nation. The benefits of having a racially diverse class are indisputable. Minority physicians are more likely to provide care to minority, underserved, disadvantaged and low-income populations.

Background: Pancreatic cancer is often locally and distally aggressive, but initial presentation as cecal perforation is uncommon.

Case Presentation: We describe a patient presenting with pneumoperitoneum, found at initial exploration to have a cecal perforation believed to be secondary to a large cecal adenoma, after palpation of the remainder of the colon revealed hard stool but no distal obstruction. Postoperatively, however, the patient progressed to large bowel obstruction and upon reexploration, a mass could now be delineated, encompassing the splenic flexure, splenic hilum, and distal pancreas.
