An innovative reconstruction of an enbloc resected composite giant chest and abdominal wall chondrosarcoma with 3D-composite mesh.

BACKGROUND: Chest wall chondrosarcomas, although common, pose unique challenges due to their aggressive nature, rarity of abdominal wall involvement, and propensity for recurrence. We highlight the critical role of meticulous surgical planning, multidisciplinary collaboration, and innovative reconstruction techniques in achieving optimal outcomes for patients with composite giant chest and abdominal wall chondrosarcoma. CASE PRESENTATION: A 38-year-old female patient presented with progressive left chest and abdominal wall swelling for two years; on evaluation had a large lobulated lytic lesion arising from the left ninth rib, scalloping eighth and tenth ribs measuring 13.34 × 8.92 × 10.71 cm (anteroposterior/transverse/craniocaudal diameter) diagnosed with chondrosarcoma grade 2. A three-dimensional (3D) composite mesh was designed based on computed tomography using virtual surgical planning and computer-assisted design and manufacturing technology. She underwent wide local excision and reconstruction of the chest and abdominal wall with 3D-composite mesh under general anesthesia. The postoperative condition was uneventful, with no recurrence at 12 months follow-up. CONCLUSION: A 3D-composite mesh facilitates patient-specific, durable, and cost-effective chest and abdominal wall reconstruction.

Isolated intramuscular cysticercosis of the forearm masquerading as malignancy.

A woman in her mid-20s presented to an Indian tertiary care hospital with pain in her left forearm. Extensive initial investigations led to a suspected diagnosis of a peripheral nerve sheath tumour; however, the pathological investigation of the excised tumour mass revealed it to be a case of isolated intramuscular cysticercosis in the forearm. Treatment for cysticercosis was commenced and the patient made a full recovery. Isolated intramuscular cysticercosis without the involvement of other organs is a rare presentation and has only been reported in a handful of case reports. We suggest that isolated intramuscular cysticercosis be considered a differential diagnosis in patients with isolated pain in their muscles and with no other symptoms, in patients with a presentation of solitary swelling and in patients at risk of parasitic infection. In addition, we emphasise the importance of histopathological examination due to the varied presentation of cysts.
