Cervical squamous cell carcinoma with isolated tibial metastasis: A case report and review of the literature

En bloc resection of cervical adenocarcinoma with late recurrence to the iliopsoas

This is a case of a 50-year-old woman diagnosed with recurrent cervical adenocarcinoma presenting with chronic and persistent low back pain. She underwent myomectomy for myoma uteri 8 years prior. Histopathology report revealed cervical cancer. She underwent chemotherapy, brachytherapy and external beam radiotherapy. All surveillance work-up, over the years, were negative until she was found to have a solitary recurrent lesion in the right iliopsoas muscle on CT scan. A multidisciplinary team of surgeons collaborated to perform wide excision of pelvic recurrence en bloc right internal hemipelvectomy, right hemicolectomy en bloc resection of external iliac artery and vein, external ilio-iliac artery interposition graft and external iliac vein-common femoral vein bypass. Final histopathologic results showed adenocarcinoma with endometrioid features with associated poorly differentiated high-grade carcinoma involving the iliopsoas, cecum and terminal ileum. Two months postoperatively, the patient is ambulating with minimal assistance.

High-grade squamous cell carcinoma arising in a tibial adamantinoma

Adamantinoma of the long bones is a rare, typically low-grade malignant tumor that frequently involves the tibia. Radiographically, adamantinoma is characteristically a lytic, intracortical, and expansile lesion with variable margins. Histologically, adamantinoma is a bimorphic neoplasm, composed of epithelial and osteofibrous elements. Herein, we describe a 72-year-old man with a long-standing tibial mass that, on imaging, rapidly developed cortical destruction with soft tissue extension. Imaging revealed no evidence of a distant site of origin. Needle core biopsy demonstrated high-grade squamous cell carcinoma, and metastasis was initially favored. However, the combined clinicoradiologic and pathologic features were most compatible with a high-grade squamous cell carcinoma arising in adamantinoma. The diagnosis was confirmed in the resection specimen. Both the age at presentation and histologic features make this case unusual and highlight a potential for misdiagnosis in the evaluation of squamous cell carcinoma-containing lesions of the tibia, reinforcing the importance of clinicoradiologic correlation in bone pathology.

Unusual sites of metastases of carcinoma cervix

We present a case of metastatic squamous cell carcinoma cervix with solitary bone metastases to the right tibia and multiple cutaneous metastases. A woman aged 52 years with cancer of the cervix and lung metastases, after 21 months of initial diagnosis and palliative chemotherapy presented with pain in the right knee and multiple nodular skin lesions. Bone scintigraphy revealed intense increased tracer activity in the proximal and mid shaft of the right tibia. Biopsy from the tibial lesion confirmed metastatic squamous cell carcinoma. The presentation, diagnosis and management of this rare case are discussed.

Metastatic cervical carcinoma masquerading as iliopsoas abscess in an HIV negative woman-diagnosed on fine-needle aspiration cytology: A case report

The most common pathology in iliopsoas region in the Indian subcontinent is tuberculosis. The iliopsoas compartment can also be affected by other conditions such as hemorrhage and tumors. However, isolated metastasis in the area is usually rare, especially in cases where the primary malignancy is undiagnosed previously. Such cases may be misinterpreted on radiological examination as psoas abscess of infectious origin. Here we present a case of metastasis in psoas muscle from a previously undiagnosed case of carcinoma cervix.
