RESUMO
It is well reported that patients who have undergone breast augmentation and subsequently develop breast cancer can successfully undergo breast-conserving therapy with preservation of their implants. However, there is a paucity of literature on the radiological investigations and surgical techniques in postmastectomy implant-reconstructed patients who develop recurrences to enable preservation of their implant-based reconstruction whilst effectively treating the local recurrence. The wide adoption of acellular dermal matrix use in prosthetic breast reconstruction in recent years has made radiological evaluation of such patients challenging. Herein presented is a case of a 37-year-old woman where wide local excision of a local recurrence abutting a peri-implant capsule following previous mastectomy and implant-acellular dermal matrix (ADM) reconstruction was performed with successful preservation of reconstruction volume (and shape) using an ADM patch to repair the capsular defect whilst retaining the implant in situ. Radiological investigation facilitated and guided the surgical planning and oncological clearance.
RESUMO
We present a case of upper limb muscle metastasis in a female patient with a history of malignant melanoma. Although melanoma is the fifth most common cancer in the UK, muscle metastases are extremely rare, with only a few cases reported in the literature. We discuss the challenge of diagnosing muscle metastasis on radiological imaging and in particular of distinguishing metastatic lesions to muscle from sarcoma. We also review the imaging findings of other published cases in a literature review. We conclude that although certain characteristic features of melanoma metastases can be identified on imaging (e.g., hyperintensity on T 1-weighted MRI), the radiological appearances are highly variable and histopathological examination is necessary to confirm the diagnosis.
