Pulmonary Alveolar Microlithiasis in a Middle-Aged Man Presenting With Respiratory Failure: A Case Report and Review of the Literature.

Pulmonary alveolar microlithiasis (PAM) is an autosomal recessive disease of the lung, characterized by diffuse deposits of intra-alveolar calcium phosphate microliths. It usually affects both sexes, presenting mostly in the second and third decades. The clinical course is highly variable, ranging from being asymptomatic to respiratory failure.

Incidental Detection of a Rare Pediatric High-Grade Fibrosarcoma in a Post-traumatic Setting: The Conundrum of Intra-Abdominal Hematoma versus Neoplasia.

Infantile fibrosarcoma (IF) is a rare malignant fibroblastic tumor that affects infants and young children, occurring most commonly in the extremities. Here, we present a 14-year-old patient with an abdominal mass incidentally detected after a blunt injury to the abdomen. The initial trauma protocol CT revealed a high attenuation mesenteric lesion in the left central abdomen suggestive of mesenteric hematoma.

The optimal approach of EBUS-FNA rapid on-site evaluation (ROSE): a five-year experience from a large academic medical center.

Introduction: Rapid on-site evaluation (ROSE) performed during endobronchial ultrasound-guided fine needle aspiration (EBUS-FNA) has shown significant value. However, ROSE may not be available for some pulmonary centers. Performing ROSE can be challenging and stressful due to time constrains for preparing, staining and reviewing the cytology slides between passes.

Obesity Is a Risk Factor Associated with -negative MALT Lymphoma of Stomach.

Objective: More than 90% of gastric mucosa-associated lymphoid tissue (MALT) lymphomas are attributed to infections. However, the pathogenesis of -negative MALT lymphomas is controversial, and additional etiologies need to be investigated.

Materials: A retrospective study of gastric MALT lymphoma cases over a 15-year period revealed 56 cases.

An Incidental Finding of Gastric Mucosa-Associated Lymphoma (MALToma) in a Sleeve Gastrectomy with Literature Review.

Mucosal-associated lymphoid tissue (MALT) lymphoma can typically be identified as a mass lesion or nodularity endoscopically and macroscopically. We report an incidental finding of a gastric mucosal-associated lymphoid tissue (MALT) lymphoma in a sleeve gastrectomy specimen with no gross examination findings.

The risk for malignancy using the Milan salivary gland classification categories: A 5-year retrospective review.

Aims: Since the six-tier Milan salivary gland classification has been introduced, there are very limited studies in literature reporting the risk stratification of the Milan classification.

Methods: We retrospectively classified a total of 285 salivary gland cytology cases into Milan reporting categories; there were 23 (8.1%) nondiagnostic, 48 (16.

The gamut of primary retroperitoneal masses: multimodality evaluation with pathologic correlation.

The retroperitoneum is a large space where primary and metastatic tumors grow silently before clinical signs appear. Neoplastic retroperitoneal diseases may be solid or cystic, primary or secondary and range from benign to aggressive in behavior. Retroperitoneal neoplasms are notable for their widely disparate histologies.

Littoral cell angioma: review of the literature and case report.

Littoral cell angioma (LCA), a primary vascular neoplasm originating from splenic red pulp littoral cells, was initially thought to be an extremely rare pathology. There have been an increasing number of cases reported in the literature. However, the etiology and prevalence of LCA is still unclear, partly due to the rarity of cases.

Intracerebral metastasis of a sinonasal teratocarcinosarcoma: a case report.

Sinonasal teratocarcinosarcoma (SNTCS) is a rare, malignant neoplasm that contains both mesenchymal and epithelial components. The mortality rate for this tumor is ∼60% within 3 years, with the average survival rate being 1.7 years.
