Soft-tissue sarcoma (STS) is a rare tumor that may occur in the upper extremity. Its presentation is delayed by slow growth and lack of symptoms. Lesions are discovered via physical and radiologic examinations, and definitive diagnosis is conducted histopathologically. We present the case of a 63-year-old man with swelling of the dorsum of the arm, nocturnal hyperhidrosis, and weight loss. Radiologic examination revealed possible malignancy and metabolically active left axillary lymph nodes. The tumor was excised, and the defect was covered using a pedicled myocutaneous latissimus dorsi flap. The distal portion of the muscle was attached to the remnant tricep brachii tendon. Postoperative histopathology revealed a highly malignant STS. The patient remained relapse-free after a regimen for adjuvant chemotherapy. Satisfactory aesthetic results and modest elbow extension were evident during the 11-month follow-up. Properly managing upper extremity STS is crucial for preventing recurrence and metastasis.

Introduction. Detecting metastases is an important part of successful breast cancer treatment. Usually, the tumor tissue first spreads to the sentinel lymph nodes. Removal of the latter during surgery and histological examination allows to assess the patient’s di­sease stage, prognosis and treatment. The literature provides more than one approach or a combination of them, allowing us to accurately identify the breast’s sentinel lymph nodes and avoid removing all axillary lymph nodes. Purpose. To review the methods of intraoperative detection of breast sentinel lymph nodes presented in the literature. Research material and methods. Publications were searched using the specialized information search system Google Scholar. Keywords used in the search: breast sentinel lymph nodes, intraoperative detection. After evaluating the exclusion criteria, the review was based on 25 scientific publications. Results. 4 individual measures and 2 combinations of them can be used to detect sentinel breast lymph nodes during surgery. The materials used can be injected in 6 different ways. Conclusions. The combination of technetium-99m radiocolloid and methylene blue can be evaluated as the best method for intraoperative detection of sentinel lymph nodes in breast cancer patients. On the other hand, due to radiation and operating costs, more attention is being paid to the use of indocyanine green, superparamagnetic iron oxide, methylene blue dye, and the detection of metastases without surgery. Superficial methods of injecting the substance should be combined with deep ones due to the possibility of detecting extra-axillary sentinel lymph nodes of the breast. Ultimately, all decisions must be made on a case-by-case basis.
