ABSTRACT

In melanoma patients, distant metastases frequently manifest in the skin, lung, brain, liver, bone, and intestine. Notably, bone metastasis predominantly occurs within the axial skeleton, with the lumbar and thoracic spines being the most affected regions. Conversely, prostate cancer often disseminates to the bone, lung, liver, pleura, and adrenal glands. The spinal column, particularly the lumbar region, frequently harbors metastases in prostate cancer cases. Given the proximity of axial lesions to the spinal cord, patients commonly experience pain, weakness, and urinary dysfunction. This article presents a compelling case report of a patient initially diagnosed with metastatic prostate cancer, who later exhibited a metastatic lesion in the thoracic spine, subsequently identified as originating from acral melanoma on the plantar surface of the right foot. Histopathological examination confirmed the presence of acral melanoma in both the spine and the right foot. The patient received comprehensive treatment for advanced melanoma from a multidisciplinary team comprising medical and radiation oncologists. Considering the overlapping pathophysiology of prostate cancer and melanoma, simultaneous screening for both diseases in cases where one is detected could yield significant benefits, including enhanced morbidity and mortality outcomes and the facilitation of early detection for secondary malignancies.

ABSTRACT

Lambl's excrescences (LEs) are delicate filiform strands formed by connective tissue located along the valve closure lines within the cardiovascular system. Most cases of these excrescences manifest without discernible symptoms, and the exact etiological factors contributing to their formation remain unknown. These excrescences may embolize to the brain, causing strokes. It is essential that all other possible causes of stroke be eliminated prior to identifying Lambl's excrescences as the cause of the stroke. Herein, we present a case of a patient who suffered a stroke, and all conventional testing for common causes of embolic strokes was ruled out. In pursuit of a comprehensive evaluation encompassing the classification of the stroke as cryptogenic, a transesophageal echocardiogram (TEE) was performed, which effectively disclosed the existence of LEs situated on the aortic valve leaflets. The patient was treated with anticoagulation and discharged with close follow-up monitoring. To culminate, the inclusion of this case within our study augments the currently scarce pool of instances that exhibit such characteristic cardioembolic phenomena, thereby accentuating the necessity for additional prospective investigations to substantiate the existence of a causative association linking LEs and cardioembolic strokes.
