Background: Cholesteatomas are growths of squamous epithelium that can form inside the middle ear and mastoid cavity and damage nearby structures causing hearing loss when located at the petrous apex. The primary goal of petrous apex cholesteatoma resection is gross total removal with tympanoplasty and canal-wall up or canal-wall down tympanomastoidectomy. At present, there is no definitive surgical approach supported by greater than level 4 evidence in the literature to date. Methods: A systematic review was conducted utilizing PubMed, Embase, and Scopus databases. Articles were screened and selected to be reviewed in full text. The articles that met inclusion criteria were reviewed for relevant data. Data analysis, means, and standard deviations were calculated using Microsoft Excel. Results: After screening, five articles were included in the systematic review. There were a total of eight pediatric patients with nine total cholesteatomas removed. Conductive hearing loss was the most common (77%) presenting symptom. Perforations were noted in seven ears (86%). Recurrence was noted in 50% of patients with an average recurrence rate of 3.5 years (SD = 1.73). Average length of follow-up was 32.6 months (SD = 21.7). Canal-wall up was the most utilized technique (60%) and there were zero noted surgical complications. Five of the seven (71%) patients that experienced hearing loss from perforation noted improved hearing. Conclusion: Due to its rarity, diagnostic evaluation and treatment can vary. Further, multi-institutional investigation is necessary to develop population-level management protocols for pediatric patients affected by petrous apex cholesteatomas.

BackgroundThere are very few studies and cases in the literature describing metastatic breast cancer in the male population, accounting for less than 1% of all cases. Of those who have been reported, the vast majority fail to survive beyond 5 years from time of diagnosis. The lack of literature in this population makes it difficult for clinicians to foresee and prepare for upcoming complications in management. One of the more serious complications in managing metastatic breast cancer is the development of pseudocirrhosis, a frequent long-term side effect of chemotherapy and/or radiation typically seen in patients with malignancy in the liver.Case PresentationWe report the case of a 48-year-old male with a completely unremarkable family, medical, and social history other than a homozygous mutation in his MTHFR gene who was diagnosed with stage IV ER/PR-positive, HER-2/neu negative, BRCA1 and BRCA2-negative breast cancer with metastasis to bone, lung, and liver who was successfully treated with a regimen consisting of radiation, Denosumab, Leuprorelin, and Anastrozole. 8 years later since initiation of treatments, he continues to survive and undergo symptomatic management of long-term side-effects of his treatments.ConclusionsTo our knowledge this is the only reported case of metastatic breast cancer with pseudocirrhosis in a male patient. It is imperative to report this unique case to help increase awareness for clinicians managing other males with breast cancer. What makes this case even more reportable is the good outcome overall as our patient remains alive and well 8 years since time of diagnosis, a relatively difficult and rare feat to achieve in end-stage breast cancer.
