Appendix diverticulosis in a patient diagnosed on pathology after laparoscopic appendectomy for appendicular mucinous mass-case report and literature review.

Diverticulum of the appendix is uncommon cause of right iliac fossa pain and inflammation with delayed diagnosis and high risk of complications, as it mimics acute appendicitis. Here we present a case of an elderly male patient who had lung cancer post-treatment. During the follow-up, appendicle lesion was discovered and suspected to be mucinous appendix. The pathology reported after appendectomy as appendicular diverticulosis without evidence of malignancy. As appendicular diverticulum is best confirmed by pathology, still its clinical presentation is difficult to be distinguished from other appendicular diseases. It is frequently linked to increased risk of cancer, particularly carcinoid tumors and mucinous adenomas.

A Very Rare Basidiobolomycosis Case Presented with Cecal Perforation and Concomitant Hepatic Involvement in an Elderly Male Patient: A Case Study.

This is a case report of Basidiobolomycosis in a 65-year-old male patient from Jizan presenting with colonic perforation and concomitant liver involvement from February 2021 to July 2021. To control the infection, the patient underwent colonic resection and segmental liver resection, as well as three antifungal drugs. The treatment was successful, and the condition was completely resolved.

Long-Term Outcome of Spinal Extranodal Rosai-Dorfman Disease: A Report of Two Cases and Systematic Review.

BACKGROUND: Rosai-Dorfman disease (RDD) is a rare pathologic entity caused by sinus histiocytosis with massive cervical lymphadenopathy. Isolated spinal involvement is an infrequent presentation of extranodal RDD. The clinical and radiologic appearance of RDD represents a diagnostic challenge. We report 2 patients with paraparesis caused by RDD of the thoracic spine and a PRISMA-style systematic review. CASE DESCRIPTION: There were 2 patients with isolated extranodal thoracic spinal RDD without cervical lymphadenopathy. One patient presented with anterior thoracic RDD and a subtotal resection. The small residual disease completely responded to the postoperative course of steroids. The second patient had extradural thoracic spine RDD, which was resected completely. A 6-month postoperative follow-up magnetic resonance imaging (MRI) scan showed local recurrence, which responded to radiation therapy. Five years follow-up of both patients showed normal neurologic functions and no recurrence on MRI scan surveillance. CONCLUSIONS: RDD is a rare occurrence and should be considered in the differential diagnosis of extradural or intradural spinal lesions. Gross total resection is recommended, and long-term clinical follow-up with MRI is advised. Residual or recurrent RDD requires steroids or radiation therapy.
