Multiple Consecutive Cervicovaginal Cytology Specimens Confirm Persistent Colonization by Cokeromyces recurvatus: Case Report and Literature Review.

The published literature on cervicovaginal cytology includes fewer than ten reported cases of Cokeromyces recurvatus identified in Pap test samples. We report a unique case of an asymptomatic 27-year-old female with persistent gynecologic tract colonization by C. recurvatus in which distinctive fungal microorganisms were identified in three samples collected over three consecutive years.

Diagnosis and Treatment of Isolated Cerebral Mucormycosis: Patient-Level Data Meta-Analysis and Mayo Clinic Experience.

BACKGROUND: Isolated cerebral mucormycosis is a rare and serious infection associated with intravenous drug abuse. METHODS: We performed a comprehensive meta-analysis of cases reported in studies and have included an unreported case from our institution. We searched PubMed/Medline, EMBASE, Scopus, Cochrane Databases, and our institution's electronic medical health records from inception through March 31, 2018. The cases were considered isolated (only affecting the cerebrum, cerebellum, or brainstem) if the absence of other primary sources of infection had been documented. Continuous variables were summarized using the median and interquartile range and categorical variables using frequencies and proportions. The relationships between variables were tested using the Wilcoxon rank sum and Pearson χ2 tests. RESULTS: A total of 130 studies (141 patients) met the eligibility requirements and were screened; 68 patients were included. The median age was 28 years (interquartile range, 24-38); 57% were men. Most patients had a history of intravenous drug abuse (82%), and 20% had positive human immunodeficiency virus findings. The lesion location was mostly supratentorial (91%), especially in the basal ganglia (71.2%). The cultures were positive in 38%, with Rhizopus the most common organism (59%). The mortality rate was 65%. The survivors were significantly more likely to have received amphotericin B (92% vs. 43%; P < 0.001) or to have undergone stereotactic aspiration (58% vs. 25%; P < 0.01). CONCLUSIONS: Isolated cerebral mucormycosis has a pooled mortality rate of 65%. The presence of lesions in the basal ganglia, rapidly progressive symptoms, and a history of intravenous drug abuse should raise suspicion for the early initiation of amphotericin B and stereotactic aspiration.

Cytomorphologic characteristics of fine needle core biopsy of multicystic peritoneal mesothelioma: a case report and review of the literature.

Multicystic peritoneal mesothelioma (MPM) is an uncommon cystic mesothelial proliferative lesion. It occurs predominantly in women of reproductive age and most commonly arises in the pelvis. The preoperative diagnosis of MPM is difficult to establish based on clinical and radiographic findings, and has therefore traditionally been diagnosed following surgical resection. Due to differing management of MPM and its differential diagnoses including both benign and malignant lesions, it would be beneficial to diagnose MPM preoperatively. We report a case of MPM in a middle aged female that was diagnosed by fine needle core biopsy and touch preparations, allowing for appropriate clinical management. The cytomorphologic features of needle core biopsy, immunocytochemical studies and differential diagnosis are discussed. Furthermore, despite its infrequency, the current case emphasizes the importance of the inclusion of this entity in the differential diagnosis of cystic lesions of the abdomen and pelvis at the time of on-site evaluation and final diagnosis, in order to avoid misinterpretation of strips of benign mesothelial cells as inadequate for diagnosis.

Fine needle aspiration diagnosis of osteitis fibrosa cystica (brown tumor of bone): a case report.

BACKGROUND: Fine needle aspiration (FNA) cytologic diagnosis of bone lesions is controversial; opponents cite its low sensitivity and proponents emphasize its cost-effectiveness, specificity and rapid turnaround time. The focus of FNA cytology is most often to exclude malignancy, which may contribute to incomplete information sharing on the part of the health care team and the published low sensitivity of diagnostic cytology of osseous lesions. It is therefore incumbent upon cytopathologists to formulate a complete differential diagnosis of osseous lesions. CASE: A 72-year-old man, admitted for severe abdominal pain, underwent diagnostic computed tomography (CT) examination that incidentally revealed multiple abdominal and pelvic lytic bone lesions. CT-guided FNA of a lesion revealed bland histiocytic and spindled cells, prominent hemosiderin pigment and scattered multinucleated cells, findings consistent with osteitis fibrosa cystica. Subsequent consultation with the medical team revealed the patient's underlying secondary hyperparathyroidism. CONCLUSION: This case emphasizes the importance of correlating clinical history and radiologic findings to the accurate cytologic diagnosis of bone lesions. The benign cytomorphologic features of brown tumor should not be overlooked or be considered nondiagnostic in the hunt for suspected malignancy. FNA allowed confident exclusion of a malignant process and prevented unnecessary surgery and its inherent risks.
