“…No clear cystic components were found. [ 9 ] In this case, the imaging findings showed a giant cystic solid mass on the right retroperitoneum and lower back, with unclear borders. The mural wall, partition, and wall nodules around the enhancement were strengthened, and most of the foci were cystic areas lacking strengthening.…”

Ratioanle: Interdigitating dendritic cell sarcoma (IDCS) is a rare sarcoma that originates from interdigitating dendritic cells in lymphoid tissue, the imaging characteristics of which are poorly defined. Pathological examination can identify the tumor, but reports on the imaging characteristics of IDCS are limited. Patient concerns: Here, we report a case of IDCS in a 48-year-old female involving the retroperitoneal area. The patient had a lumbar mass on her right lower back for 4 years, and which started increasing in size 1 year before. Diagnoses: An irregular soft tissue mass (10.1cm × 8.5 cm in size) in the right lower back of retroperitoneum was detected by CT examination with unclear borders, uneven density, and necrosis. The solid components of the mass were significantly enhanced on postcontrast imaging. The soft tissue was irregular and uneven. Cystic solid masses were observed on MRI examination in the right retroperitoneum, lateral abdominal wall, waist, and back. Necrosis, hemorrhage, and cystic transformation were observed inside the lesion. The cyst wall, separation, and wall nodules were significantly enhanced on the postcontrast image. No distant metastasis was observed. Postoperative pathology confirmed the diagnosis of IDCS. Interventions: The patient underwent surgical resection. The resected margin was positive, and the patient received adjuvant radiotherapy 2 months after the surgery. Outcomes: Twelve months after radiotherapy, the patient's chest CT showed multiple metastases in both lungs. The patient was started on combination chemotherapy of doxorubicin and ifosfamide, and the follow-up is still ongoing. Lessons: Imaging provides a unique advantage to determine the extent of the IDCS, the invasion of adjacent tissues, and the presence or absence of distant metastases.

“…Adjuvant radiotherapy does not significantly improve the overall survival time or reduce recurrence rates, and systemic chemotherapy is the main treatment for patients with distant metastasis. 12 The chemotherapy regimens for patients with metastatic IDCs include CHOP (cyclophosphamide, adriamycin, vincristine, prednisone), ABVD (adriamycin, bleomycin, vincristine, dacarbazine), and ICE (ifosfamide, carboplatin, etoposide). However, the anticancer efficacy of these regimens is very limited.…”

We report a case of interdigitating dendritic cell sarcoma (IDCS) originating from the adrenal gland. A 57-year-old middle-aged woman with no previous history of malignancy came to our hospital after color Doppler ultrasound revealed a right adrenal mass. An abdominal computed tomography scan also showed an adrenal mass. Postoperative pathology confirmed the diagnosis of IDCS. After complete surgical removal of the adrenal tumor, the patient has been disease-free for 1 year. IDCS may have a good prognosis after surgical resection. To our knowledge, this is only the second reported case of IDCS in the adrenal region.

“…Interdigitating dendritic cell sarcoma is an extremely rare disease, with only 100 cases reported in the English literature (90). Clinically, it manifests as a painless mass in middle-aged men, with a male to female ratio of 3:2.…”

“…Clinically, it manifests as a painless mass in middle-aged men, with a male to female ratio of 3:2. Interdigitat-ing dendritic cell sarcoma mainly involves the lymph nodes, but extranodal involvement has been reported in one-third of cases, including in the lungs, skin, breast, bone, liver, spleen, and small intestine (90). Imaging manifestations vary depending on the disease site (Fig 26).…”
