“…[ 2 , 8 ] In most patients, EAML arises in kidney and its symptoms are similar with RCC. [ 9 , 10 ] EAML can occur in other organs such as the lung, liver, pancreas, bladder, prostate, uterus, ovary, vulva, vagina, and bone. [ 3 , 11 ] In the current report, the tumor of 6.0 × 5.2 × 7.0 cm in size was located in the left kidney.…”

Rationale:Epithelioid angiomyolipoma (EAML) is an extremely rare disease. It commonly occurs in middle-aged females and mainly involves the kidney. Histological and immunohistochemical examination play important roles in differentiating EAML from renal cell carcinoma (RCC) and poor-fat angiomyolipoma (AML).Patient concerns:Here, We report the imaging phenotype, as well as the pathological findings of a case of EAML in a 39-year-old female.Diagnoses:Preoperative noncontrast computed tomography (CT) scan revealed a 6.0 × 5.2 × 7.0 cm soft tissue mass with necrosis, located in the left kidney. On contrast-enhanced CT images, aprogressive enhancement pattern was observed. CT angiography did not show any enlarged vessels or vascular malformation. Abdominal MRI showed a well-circumscribed solid mass with a heterogeneous signal on T1-weighted and T2-weighted images. Ultrasonography of the abdomen demonstrated a hypoechoic mass with abundant blood flow. This patient underwent radical nephrectomy. The pathologic diagnosis was EAML.Interventions:This patient underwent operative resection of the tumor. The resection margins were negative for the neoplastic proliferation and no distant metastases were found. The patient did not receive advanced radiotherapy or chemotherapy.Outcomes:Four months after surgery, the follow-up CT scan did not reveal any local recurrence or distant metastases.Lessons:This case adds to the experience with EAML by summarizing its imaging characteristics as well as reviewing the literature. Additionally, we described the state-of-the-art management of the management of this rare tumor.

“…In most patients, IDCS arises in a peripheral lymph node and its symptoms are similar to lymphadenitis. [ 3 , 8 ] The next most commonly affected organ is the liver. [ 3 , 7 ] In these patients with extranodal IDCS, systemic symptoms such as weight loss and fever are more common.…”

“…[ 1 ] Most IDCS occurs in the lymph nodes (particularly in the neck, mediastinum, and axilla) [ 2 ] ; however, about 1/3 are located in the extranodal organs such as the lung, skin, breast, bone, liver, spleen, and small intestine. [ 3 – 5 ] Histological findings of IDCS show the tumor cells are medium to large spindle shaped with indistinct cell borders that form a whorled growth pattern. [ 6 , 7 ] Until now, only about 100 cases of IDCS have been reported in the English literature and surgical resection remains the mainstay of treatment for early-stage, localized disease.…”

Rationale:Interdigitating dendritic cell sarcoma (IDCS) is an extremely rare disease. It commonly occurs in middle-aged males and mainly involves the lymph nodes. Pathological examination plays an important role in differentiating from other tumors, but far less published literature focuses on the imaging characteristics of IDCS.Patient concerns:Here, we reported a case of IDCS in a 52-year-old male involving the pelvis with medical imaging and pathologic findings.Diagnoses:Preoperative unenhanced CT scan revealed a 6.0 × 6.3 × 8.0 cm mass with density equal to that of adjacent muscle, located in the pelvis. On contrast-enhanced CT images, the tumor presented apparent homogeneous enhancement. CT angiography showed that the tumor was supplied by the branches of inferior mesenteric artery. Pelvic magnetic resonance imaging manifested a lobulated solid mass with low signal on T1-weighted and intermediate to high signal on T2-weighted images. Simultaneously, significantly high signal intensity was exhibited on the diffusion-weighted images. This patient underwent operative resection of the tumor. The pathologic diagnosis was IDCS.Interventions:This patient underwent operative resection of the tumor. The resection margins were negative for the neoplastic proliferation and no distant metastases were found. The patient did not receive advanced radiotherapy or chemotherapy.Outcomes:Three months after surgery, the follow-up CT scan did not reveal any recurrence or metastases.Lessons:This case adds to the experience with IDCS by summarizing its characteristics as well as reviewing the literature.

“…The role of PET scans in these rare tumors is also unclear. IDCS has been shown to be FDG-avid in some cases, 23 and PET can be used to monitor treatment response. 24,25 In the present case, PET scan detected residual disease and prompted surgical reintervention.…”
