Axillary lesion in a young adult ends up to a peculiar diagnosis: primitive neuro-ectodermal tumor (PNET) of ulnar nerve: a rare case report.

Introduction and importance: Primitive neuro-ectodermal tumor (PNET) is a highly aggressive tumor composed of small round blue cells, mostly developing in children and young adults. Being a member of Ewing's Sarcoma Family of Tumors (ESFT); it has been discussed in two subcategories of central and peripheral PNET. PNETs of peripheral nerves are very uncommon pathologic findings, as to the best of our knowledge only 12 well-documented cases have been yet reported. Case presentation: A 30-year-old male presented with progressive paresthesia of his right hand's little finger and painless swelling of the right axilla. Magnetic resonance (MR) neurography demonstrated a heterogeneous, high-signal, round mass within the right axilla fossa in proximity to the medial aspect of brachial plexus branches. The clinical and radiological study failed to an accurate diagnosis, thus surgical resection of the tumor was done for tissue evaluation. Histopathologic study of the lesion revealed a neoplasm comprising sheets of small, round, blue cells (Hematoxylin and Eosin stain), which immunohistochemically consisted with the diagnosis of PNET. Clinical discussion: The differential diagnosis of axillary fossa masses, focusses on peripheral nerve tumors like Schwannoma and PNET. MR neurography aids in evaluation, but tissue diagnosis remains crucial. Treatment involves surgical resection, chemotherapy, and radiotherapy tailored to individual patients. Conclusion: Although pPNET is not apparently the first differential diagnosis coming to mind when encountering a rapidly growing mass in the axillary fossa with peripheral nerve origin, its highly malignant behavior, makes it crucial to be considered in the differential diagnoses.

Platelet-rich plasma for treatment of female stress urinary incontinence.

INTRODUCTION AND OBJECTIVE: Stress urinary incontinence (SUI) poses a significant burden on affected individuals, impairing their quality of life and causing embarrassment due to involuntary urine leakage during activities such as sneezing or coughing. While conservative and surgical treatments exist, a subset of patients experiences persistent symptoms despite these interventions. This review provides insights into the potential role of platelet-rich plasma (PRP) as a therapeutic adjunct for patients with SUI that does not respond to conventional non-surgical or surgical treatments. METHODS: We conducted a literature review of studies in English to evaluate PRP efficacy in managing SUI. RESULTS: The studies conducted on PRP therapy suggest that it is an effective and safe treatment option for SUI in women. PRP injections, when used alone or in combination with other therapies, have shown significant improvements in SUI symptoms. Moreover, these studies indicate that PRP injections offer a less invasive and low-risk alternative to surgical procedures for managing SUI, which could lead to shorter recovery times. CONCLUSION: The efficacy of PRP therapy is evidenced by significant reductions in SUI symptoms, as well as improvements in bladder function variables, without significant adverse effects reported. However, further research is necessary to establish the long-term effectiveness and safety of PRP therapy for managing SUI in diverse patient populations. Additionally, ongoing evaluations of PRP therapy in combination with other interventions will be essential for optimizing treatment outcomes and broadening the potential applications of PRP in the management of SUI.

Ectopic pancreatic tissue in a cholecystectomy specimen: A rare incidental pathologic finding.

Ectopic pancreatic tissue is a rare congenital abnormality defined as the abnormal location of pancreatic tissue outside the anatomical site of the pancreas without any anatomical or vascular connection to it, which is often discovered incidentally. This is a case of a 40-year-old man who was admitted to our surgical department for emergency cholecystectomy due to acute gangrenous cholecystitis. Preoperative ultrasound imaging was indicative only of multiple stones in the gallbladder. Postoperative histopathological examination revealed an area of wall thickening in the neck region of the gallbladder consists of ectopic pancreatic tissue. We emphasize the role of a precise pathologic examination even in routine surgical specimens such as a cholecystectomy specimen, since no preoperative evaluation can be affirmative of such incidental but momentous histopathologic findings. Anatomical pathologists must be aware of the rare presentation of Ectopic Pancreatic Tissue (EPT) in gallbladder which may masquerade as a malignancy.
