Abstract PDF: Lipomas are one of the most common mesenchymal tumors in the human body, exhibiting a heightened prevalence between the ages of 40 and 60 years. However, primary intraoral lipomas are rare. Myxoid lipoma, which is characterized by abundant mucoid components, is a particularly rare histological subtype of lipoma. This study presents two cases of myxoid lipoma that occurred outside the common age range for occurrence, one in the right submandibular area of a 67-year-old male and the other in the lower lip of a 3-year-old child. Through these case reports, the aim was to introduce myxoid lipoma, a rare subtype affecting facial areas, and provide a brief review to assist in the differential diagnosis, emphasizing the importance of pathological assessment. Even in age groups and anatomical locations not typically associated with lipomas, it is crucial to emphasize the necessity of careful evaluation.

Connective tissue diseases (CTDs) can affect all compartments of the lungs, including airways, alveoli, interstitium, vessels, and pleura. CTD-associated lung diseases (CTD-LDs) may present as diffuse lung disease or as focal lesions, and there is significant heterogeneity between the individual CTDs in their clinical and pathological manifestations. CTD-LDs may presage the clinical diagnosis a primary CTD, or it may develop in the context of an established CTD diagnosis. CTD-LDs reveal acute, chronic or mixed pattern of lung and pleural manifestations. Histopathological findings of diverse morphological changes can be present in CTD-LDs airway lesions (chronic bronchitis/bronchiolitis, follicular bronchiolitis, etc.), interstitial lung diseases (nonspecific interstitial pneumonia/fibrosis, usual interstitial pneumonia, lymphocytic interstitial pneumonia, diffuse alveolar damage, and organizing pneumonia), pleural changes (acute fibrinous or chronic fibrous pleuritis), and vascular changes (vasculitis, capillaritis, pulmonary hemorrhage, etc.). CTD patients can be exposed to various infectious diseases when taking immunosuppressive drugs. Histopathological patterns of CTD-LDs are generally nonspecific, and other diseases that can cause similar lesions in the lungs must be considered before the diagnosis of CTD-LDs. A multidisciplinary team involving pathologists, clinicians, and radiologists can adequately make a proper diagnosis of CTD-LDs.

Abstract PDF: A rare case of telangiectatic osteosarcoma of the sphenoid bone was reported. The patient was a 27-year-old male and had suffered from left eye protrusion and diplopia for three months. Radiologically, a lobulated osteolytic lesion was located between sphenoid and left temporal bone. Pathologically, the tumor had multiloculated blood filled cystic vascular spaces and osteoid formation by malignant spindle osteoblast cells. The differential diagnosis of this rare entity from aneurysmal bone cyst was important radiologically and pathologically. This case is the second case of telangietatic osteosarcoma of the sphenoid bone followed by a case of Whitehead RE and Melhem ER in 1998.

Abstract PDF: Hepatocellular carcinoma represents approximately 90% of the primary liver cancers. Recently, its incidence tends to be increased. Thirsty seven cases from 1986 to 1991 diagnosed as hepatocellular carcinoma by resection were analyzed to know their histopathologic feature and related clinical findings. The average age at the time of resection was 53.1 years, with frequent occurrence in third and fourth decades. Microscopically, the trabecular type was the most frequent growth pattern (35.1%) and classic hepatocyte-like cell type was the most frequent cell type (75.7%). The tumors are mainly moderately differentiated and frequently associated with liver cirrhosis. In comparison of cytological differentiation with liver cirrhosis, there was a tendency for well-differentiated tumors to arise in cirrhotic livers more often than poorly differentiated tumors, and the tendency was statistically significant. But differentiation and tumor size did not show significant correlation. Also statistically significant correlations were not observed between the level of alpha-fetoprotein and tumor size, and between the level of alpha-fetoprotein and differentiation.

Abstract PDF: The authors developed a comfortable program for routine work of surgical pathology. We used IBM PC (80386) and Foxbase plus program. The main function of this program was automatic coding and concurrent surgical report printing. During gross printing, previous biopsy number and its diagnosis were automatically searched and printed below gross description. The reported data were stored during surgical report printing simultaneously, and thus the typist's workload became considerably reduced. Search for specific cases could be performed by patient's name, surgical number, hospital number, diagnostic code numbers (SNOMED code micro glossary), and certain disease entities on very short duration.
