RESUMEN
INTRODUCTION AND IMPORTANCE: Sclerosing angiomatoid nodular transformation (SANT) of the spleen is an extremely rare benign lesion. CASE PRESENTATION: Here, we describe the case of a 52-year-woman who was diagnosed with sclerosing angiomatoid nodular transformation of the spleen. Abdominal contrast-enhanced CT revealed a solid lesion in the splenic hilum that was slowly enhanced between the portal venous and equilibrium phases incidentally. Fluorodeoxyglucose positron emission tomography (FDG-PET) revealed FDG accumulation within the mass, with a maximum standardized uptake value (SUVmax) of 2.57. Based on these findings, the patient was scheduled for laparoscopic splenectomy. The total operating time was 193 min, and the intraoperative blood loss was 20 ml. The resected specimen was 9.0 × 8.4 × 5.6 cm and dark brown in colour with a large central stellate fibrotic scar. CLINICAL DISCUSSION: Pathological examination revealed nodular angioma lesions and the proliferation of fibrotic interstices and inflammatory cells. We could diagnose the SANT by the only HE staining without Immunohistochemical staining. CONCLUSION: Although SANT is a rare benign lesion, which is difficult to definitively diagnose based on preoperative imaging findings alone, it should be considered in cases of solitary splenic lesions, and we recommend performing LS and subsequent histological examination for the diagnosis of this disease.
RESUMEN
Introduction and Importance: Lateral lymph node dissection (LLND) for recurrent lateral pelvic lymph node metastasis could be the only surgical treatment to improve its prognosis, but is difficult and challenging technically. Case Presentation: A 75-year-old Japanese man who underwent a radical laparoscopic intersphincteric resection to treat double lower rectal cancer. Computed tomography and MRI showed lower rectal wall thickening and bilateral lateral lymph node swelling. The authors scheduled and performed the LLND for recurrent lateral pelvic lymph nodes after ISR by the totally extraperitoneal (TEP) approach. The bottom of the obturators lymph node (#263D) were positive for metastasis histologically. Clinical Discussion: The TEP approach is an especially effective option for the treatment of bilateral LLND. Conclusion: Herein, the authors introduce our surgical technique: successful challenging treatment of the LLND by the TEP approach after intersphincteric resection of the lower rectum.
RESUMEN
RATIONALE: Postoperative recurrence of congenital diaphragmatic hernia (CDH) in adults is very rare. There is currently no precedent and no established treatment. We encountered a case of CDH which recurred 57 years, postoperatively. PATIENT CONCERNS: A 57-year-old man with dyspnea on exertion was referred to our hospital. He had undergone surgery at the same hospital for CDH when he was 46 days old. DIAGNOSIS AND INTERVENTIONS: Laboratory studies, except diagnostic imaging and spirometry, were otherwise within normal limits. He was diagnosed with recurrent CDH based on computed tomography and underwent laparoscopic surgery. OUTCOMES: His postoperative course was uneventful, and there was no recurrence on follow-up. LESSONS: We reported our encounter with a case of recurrent CDH, more than 50 years after the initial surgery. When managing diaphragmatic hernias, prompt surgical treatment, with consideration to prior surgical history for CDH, leads to satisfactory results.
