To determine the prevalence of immunocytochemical positivities for a panel of antibodies in benign and malignant cells in effusions with known follow‐up in order to use these as diagnostic markers. Besides their ability to identify malignant epithelial cells their contribution to the differential diagnosis between carcinomatoses and mesotheliomas was investigated. 101 tumour cell positive and 53 negative effusions were stained with 12 different antibodies. Results were scored semiquantitatively per cell type. Furthermore, DNA‐image cytometry was performed. While prevalence of Ber‐EP4 positivity was 95.4% in metastatic carcinoma cells, it was 0% in those from mesotheliomas. No cell type reacted with this marker in benign effusions (0%). Ber‐EP4 correctly differentiated between metastatic carcinoma and mesothelioma in 98.0%. Prevalence of DNA‐aneuploidy was 95.4% in metastatic carcinomas, 57.1% in mesotheliomas and 0% in reactive effusions. Combining immunocytochemistry (Ber‐EP4 positivity) and DNA‐image cytometry (aneuploidy) results in a 100% detection of metastatic carcinomatoses and 57.1% of mesotheliomas. Both markers furthermore allowed a correct differentiation of these entities in 98%.

To determine sensitivity and specificity of different antibodies for the immunocytochemical detection of malignant cells in diagnostically equivocal effusions in comparison with those achieved by DNA‐image cytometry. 65 cytologically doubtful effusions of the serous cavities were stained with twelve antibodies. Furthermore, DNA‐image cytometry was performed. Data were correlated with patient follow‐up. Sensitivity of cellular staining of Ber‐EP4 for the identification of malignant cells was 77.8%, specificity of absent staining for benign cells was 100%. Positive predictive value for the identification of malignant cells was 100%, negative value 65.5%. Sensitivity of DNA‐aneuploidy for the identification of malignancy was 82.9%, specificity of DNA‐non‐aneuploidy for benignity 94.7%. The positive predictive value of DNA‐aneuploidy for the occurrence of malignant cells was 96.7%. Negative predictive value of DNA‐non‐aneuploidy was 72.0%. Combining immunocytochemistry applying Ber‐EP4 only and DNA‐cytometry in equivocal effusions resulted in a sensitivity of 88.9% for the identification of malignant cells associated with a 95.0% specificity. Positive predictive value was 97.7%, the negative one 79.2%.

Context.— Both salivary lymphadenomas (LADs) and Warthin-like mucoepidermoid carcinoma (MEC) contain components of epithelium and lymphoid stroma and their differential diagnosis can be difficult on the basis of morphology alone. Objective.— To clarify whether Warthin-like MEC was diagnosed as a LAD, and to compare their clinicopathologic features. Design.— A total of 16 LAD cases were analyzed for MAML2 rearrangement by using fluorescence in situ hybridization, and the clinical, histologic, immunohistochemical, and prognostic features were compared between MAML2 rearrangement–positive and MAML2 rearrangement–negative groups. Results.— Among the 16 cases investigated, 9 harbored a MAML2 rearrangement and were reclassified as Warthin-like MEC. The remaining 7 cases were classified as LADs with 1 nonsebaceous and 6 sebaceous cases. The patients with Warthin-like MEC had a wider age range (10–75 years) than the patients with LADs (36–68 years). Histologically, 2 of the 9 Warthin-like MECs (22.2%) showed focal invasion, whereas all the LADs had complete capsules. Warthin-like MECs exhibited a diverse epithelial cell morphology, including basaloid, glandular, cuboidal, epidermoid, with mucinous cells, although these cytologic features were seen only focally in some cases. Nonsebaceous LAD was composed of basaloid and glandular epithelial cells predominantly. In sebaceous LAD, the epithelial cells were composed of basaloid and large foamy sebaceous cells. In all cases, the stroma was composed mainly of lymphocytes accompanied by lymphoid follicles, although plasma cell infiltration could be much heavier in Warthin-like MEC. All the patients had a good outcome after a longer follow-up (3∼166 months). Conclusions.— Warthin-like MEC can be misdiagnosed as a LAD owing to overlap in clinicopathologic features of the 2 entities. Careful histologic evaluation and detection of MAML2 rearrangement can facilitate their differential diagnosis.

DNA‐image‐cytometry and antibodies directed against the Lewis X‐ and the 486p 3/12 antigen were applied to improve diagnostic accuracy of urinary cytology for the detection of bladder cancer. Cytology, immunocytology and DNA‐image‐cytometry were performed in spontaneously voided urine samples and barbotage bladder washings from 71 patients. The DNA content was determined using the CM‐1 Cytometer according to the recommendation of the ESCAP Consensus Report on Standardization of DNA‐image‐cytometry (1995). For immunocytological examination we used the monoclonal anti Lewis X antibody P‐12 and antibody 486p 3/12. All patients underwent subsequent cystoscopy and for any suspicious lesion biopsy or transurethral resection was done. Histological findings revealed 31 patients with transitional cell carcinomas of different stages and grades of malignancy. 40 patients had various benign diseases of the urinary bladder. Cytology yielded a sensitivity of 68% and a specificity of 100%. DNA aneuploidy was detected in 81% of cancer patients with a specificity of 100%. By combination of these two methods the overall sensitivity increased to 87%. Immunocytology with Lewis X and 486p 3/12 antibodies showed reactivity in 84% and 87% in combination with a specificity of 80% and 70%, respectively. By combining urinary cytology, immunocytology and/or DNA‐image‐cytometry the overall sensitivity increased to 94% with no change in specificity. DNA‐image‐cytometry should be used to evaluate particularly urothelial cells suspicious for malignancy in urinary specimens. Because of low specificity the monoclonal antibodies against Lewis X‐ and 486p 3/12 antigens are not helpful in screening for bladder cancer. Nevertheless, their high sensitivity may justify their use in case DNA image cytometry is not available and in the follow up of patients with transitional cell carcinoma.

During a project in which regenerative changes were studied in autotransplanted canine kidneys, intranuclear crystals were seen in a small number of tubular epithelial cells. These crystalline structures were seen in the control specimens and also in regenerating specimens; the main differences being in size and number of them. The control specimens showed a few tubular epithelial cell nuclei almost completely occupied by large crystals that were not membrane bound. Subsequent follow-up biopsies of the same kidneys contained similar intranuclear crystals but of a much smaller size. Some of these nuclei contained several small crystals. The small crystals occurred at one week following transplantation and were seen even four weeks following transplantation. As time passed, the small crystals appeared to fuse to form larger crystals.

AbstractBreast tuberculosis is a rare form of extrapulmonary tuberculosis which tends to affect females of reproductive age, and is much rarer in males, postmenopausal women, and pre-pubescent girls. It is difficult to diagnose because it can mimic benign conditions such as a fibroadenoma, as well as malignant diseases like a carcinoma. It is also particularly difficult to distinguish breast tuberculosis from granulomatous mastitis, so other possible diagnoses should be ruled out first. The diagnosis of breast tuberculosis has three essential pillars: clinical examination, radiological evaluations, and histopathological sampling. Radiological evaluations are not only critical in diagnosis but are also important in the planning of the treatment and during the follow-up. This paper aims to review the imaging findings and the differential diagnosis of breast tuberculosis.

Acute necrotizing encephalopathy (ANE) is a rare para-infectious encephalopathy that classically occurs in children. However, ANE should be considered in the differential diagnosis of adults with symmetric brain lesions after a prodromal illness given recent reports of coronavirus disease of 2019 (COVID-19) to presumably cause ANE in adults. We report a case of a 29-year-old male presenting with fever, malaise, and rapid deterioration into coma. Brain magnetic resonance imaging revealed multifocal symmetric areas of diffusion restriction and surrounding vasogenic edema involving bilateral thalami, pons and cerebellar hemispheres with a core of susceptibility artifact, and minimal thalamic contrast enhancement, most consistent with ANE. Extensive infectious workup revealed isolated Escherichia coli and Neisseria gonorrhoeae in his urine. Despite the severe encephalopathy on initial presentation, the patient improved with intravenous antibiotics and supportive management with minimal residual deficits at 9 months follow-up. We aim to provide an overview of the radiological features, differential diagnosis, treatment and prognosis of ANE. Becoming familiarized with this rare but devastating disease will improve detection, treatment, and ultimately prognosis, especially in the era of a new pandemic.

Vulvar Mass

Smooth muscle tumors arising in the vulva are rare. Leiomyosarcoma is the most common variant of vulvar sarcoma, and very few cases have been reported during pregnancy. A 36-year-old woman presented with a progressively enlarging vulvar mass during pregnancy, diagnosed as a Bartholin's gland cyst. The lesion was resected at 38 weeks of gestation during cesarean section and diagnosis of myxoid leiomyosarcoma of the vulva was made. Six weeks later the patients were referred to our center and submitted to wide vulvar excision with groin lymph node dissection that revealed the presence of a small residual focus of leiomyosarcoma. At 30 months of follow-up the patient was well without any sign of recurrent disease. Leiomyosarcoma should be included in the differential diagnosis of vulvar masses; progressively enlarging vulvar lesion should be biopsied even during pregnancy. Leiomyosarcoma should be considered in the differential diagnosis of vulvar mass.
