Further emphasis on ergonomic instrument design is needed to allow all orthopedic surgeons to operate as safely and effectively as possible.Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal tumors with a natural history ranging from indolent benign lesions to ones with an aggressive clinical course including distant metastases. Recent reports have suggested that mTOR inhibitor sirolimus and related drugs show some benefit in non-tuberous sclerosis complex PEComas. However, therapeutic options for patients who progress on sirolimus are very limited. We describe a patient with metastatic uterine PEComa, who progressed on mTOR inhibitor everolimus but had a rapid and durable response to nab-sirolimus.Introduction Histopathologic specimen examination of surgically isolated organs and tissues yields valuable information regarding a disease process and plays a vital role in the future management of a patient. Our aim was to account for the common diagnosis yielded from histopathological specimens of the obstetrics and gynecology department and to determine if all the obstetric and gynecological specimens should be routinely sent for histopathology. Methods A retrospective, cross-sectional study was conducted at the histopathology unit of a tertiary care hospital in Peshawar. Data were acquired for all gynecological and obstetric specimens sent for histopathology for analysis to the histopathology unit during August 2018 and July 2019. Any sample that was not sent via surgical excision was excluded from the study. Results A total of 922 samples were sent for histopathological analysis in the tertiary care hospital. The mean age of patients who had their specimens sent for pathology was 40.78 ± 10.81 years. Most of the samples sent were of the uterus (458) and the age 31-50 years (270) had the highest proportion of histopathological specimens. Normal ovaries (64.4%) and fallop
