There are various methods for reconstructing defects caused by Mohs micrographic surgery (MMS). However, there are limits to the reconstruction methods that can be used if the defect is large. An 85-year-old woman presented with a 2.4×2.2 cm hyperkeratotic plaque on her right temple for 2 years. A skin biopsy was performed for a diagnosis. Histopathology confirmed squamous cell carcinoma, and MMS was performed to completely remove the tumor. A total of three MMS stages were performed intraoperatively to confirm margin clear, resulting in a skin defect measuring 5.0×4.5 cm. To reconstruct the large defect, a splitted full thickness skin graft was performed, taking into account the site, size, and function of the defect. Each skin graft was harvested from the submental area and a tie-over bolster dressing was applied to the recipient site. To date, the surgical site has remained free of surgical complications or tumor recurrence.

Purpose: Diffuse sclerosing variant papillary thyroid carcinoma (DSV-PTC) is a rare and aggressive subtype of PTC.Preoperative diagnosis is challenging owing to the overlapping of imaging characteristics with those of other thyroid conditions. This study aimed to evaluate the accuracy of preoperative ultrasound (US) in predicting DSV-PTC and to identify significant diagnostic factors. Methods: This retrospective study analyzed 34 patients who were preoperatively suspected of having DSV-PTC based on US findings and later underwent thyroidectomy. Patients were divided into 2 groups based on the final histopathological diagnosis: DSV-PTC and non-DSV-PTC. Demographic, radiological, and pathological characteristics were also compared. Results: Only 32.4% of patients initially suspected of having DSV-PTC were confirmed postoperatively. Among the US features, the Korean Thyroid Imaging Reporting and Data System (K-TIRADS) score 5 was significantly associated with DSV-PTC (P = 0.038), whereas other radiological factors, including echogenicity and microcalcifications, were not. The histopathological features, such as tumor size, BRAF and TERT mutations, vascular invasion, and lymph node metastasis, showed no significant differences between the groups. Conclusion Preoperative US has limited accuracy (32.4%) in diagnosing DSV-PTC. Because of the aggressive treatment recommendations based on preoperative suspicion, clinicians should carefully consider the limitations of imaging. Further studies incorporating fine-needle aspiration or core needle biopsy are required to improve diagnostic accuracy.

A 13-year-old neutered male Shih Tzu presented with diffuse intestinal thickening extending from the lower part of the duodenum to the middle part of the jejunum. A portion of the jejunum was biopsied and submitted for histopathological diagnosis. Microscopically, the villi of the mucosal layer were thickened and atrophied, and round tumor cells had infiltrated the intestinal epithelial cells, crypt epithelial cells and lamina propria. Immunohistochemically, the neoplastic cells were immunoreactive to CD3. Based on these results, the intestinal mass from jejunum was diagnosed as epitheliotropic intestinal T-cell lymphoma.

A case of xanthogranulomatous metritis in a 5-year-old Korean short-haired cat is presented. Yellowish-white nodules, 1 to 2 cm in diameter and protruding from the perimetrium, were detected. Histopathological examination revealed extensive inflammatory nodules extending from the endometrium to the perimetrium. The inflammatory nodules primarily consisted of numerous macrophages, along with a smaller number of multinucleated giant cells and lymphocytes. Immunostaining for Iba-1 and Major Histocompatibility Complex class II showed positive reactions in macrophages and multinucleated giant cells. Based on these findings, a diagnosis of xanthogranulomatous metritis in the feline uterus was diagnosed. Because xanthogranulomatous metritis could be clinically diagnosed as a neoplastic lesion, it is considered to have important obstetric value in the differential diagnosis.
