Forshal type IE appendiceal intussusception: A case report.

INTRODUCTION: Appendiceal intussusception is a rare condition. Clinical features are not specific for it. Patients may present with abdominal pain and vomiting. These symptoms represent a variety of abdominal pathology. Preoperative diagnosis is difficult because of the non-specific clinical features. We present a case report of a child who initially presented with ileocolic intussusception. CASE PRESENTATION: This is a case report of a 5-years-old boy with abdominal pain and vomiting. He had an ileocolic intussusception 2 days back, and was successfully managed by hydrostatic reduction and discharged. On ultrasonography, an intussusception was identified in the ileocaecal region. Hydrostatic reduction failed this time and laparotomy was performed. On laparotomy, there was complete intussusception of the appendix with normal ileocaecal junction. Appendectomy was performed. Post-operative period was uneventful. DISCUSSION: Appendiceal intussusceptions are mostly diagnosed intra-operatively. The clinical features may mimic various other acute and chronic abdominal conditions. Type IE appendiceal intussusception, as described by Forshal, is a rare condition. Appendectomy with a rim of the caecum is the procedure of choice. CONCLUSION: Though ileocaecal intussusceptions are common in children, appendiceal intussusceptions are rare and are usually diagnosed during the operative procedure. Radiologists and pediatric surgeons should be aware of this rare entity. Appendectomy is the treatment of choice in most of the appendiceal intussusceptions.

Myopericytoma in right inguinal region: A rare case report from Nepal.

INTRODUCTION: Myopericytoma is a rare mesenchymal soft tissue tumor that originates from perivascular myoid cells and mostly benign in nature. With a slight male predisposition, it occurs more commonly in the lower extremities with an insidious and painless presentation. Contrary to the usual, our patient was with a rare presentation in the inguinal region with a dull aching pain. CASE PRESENTATION: We herein report a case of a 64-year-old female patient with myopericytoma, the first of its kind reported in Nepal, present in the right inguinal region and surgically removed. The mass was single with dull aching pain, non-tender, globular, smooth, mobile, covered with skin and, had been slowly growing for 1 year and had started bleeding for 4 days. On complete surgical excision and subsequent biopsy, a nodule with thin-walled blood vessels and spindle-shaped cells having indistinct cell border, eosinophilic cytoplasm, and oval to spindle-shaped nucleus was observed, features consistent with those of myopericytoma. DISCUSSION: Myopericytoma can occur in different sites in the body. Its differential diagnoses in the inguinal region include inguinal hernia, lipoma, or an inguinal lymphangioma. Histopathological analysis and immunohistochemistry (IHC) staining are used for diagnosis and confirmation. CONCLUSION: Myopericytomas are rare and have a substantial propensity to be misdiagnosed as other soft tissue tumors such as sarcomas due to significant overlap in their presentation and histological features. Complete surgical excision of mass is the curative therapy.
