A 47-year-old man presented to our referral center in November 2017, with a history of EMC of the right shoulder improperly excised with unplanned microscopic positive surgical margins (R1). The patient underwent debulking of the primary mass in September 2017 in a non-referral center, without a preoperative core-needle biopsy. The histological examination diagnosed EMC. No post-operative treatments were provided. At our first evaluation, the patient did not show macroscopic residual disease or distant metastasis both at the clinical and the radiological assessment. The pathological review of the excised specimen confirmed the diagnosis of EMC. After MTB discussion a “watch and wait” approach was adopted. After a 4-months follow-up, the clinical examination showed an elastic soft painless mass in the right shoulder. A Magnetic Resonance Imaging (MRI) of the shoulder was performed, showing a 35 × 15 mm intramuscular solid mass (Fig. ) within the right deltoid muscle. Computed Tomography (CT) did not reveal distant metastasis. The case was discussed in our MTB where the decision was made for preoperative RT, with a total dose of 50 Gy (fractionated in 200 cGy/die) which was a administered with Rapidarc technique. Post radiotherapy MRI performed 3 weeks later showed a partial radiological response, with a mass measuring 16 × 6 mm (Fig. ).\nIn July 2018, a wide surgical resection including the right anterior deltoid muscle and the lateral margin of the right pectoralis major muscle was performed, with a planned macroscopic margin of minimum 3 cm and the complete excision of the scar and the field of the previous surgery. The defect was reconstructed by right latissimus dorsi myocutaneous flap and polypropylene prosthesis (Figs. and ).\nThe size of the excised specimen was 23.5 × 10 × 3.5. Pathological examination was negative for viable tumor cells, showing only a fibrous subcutaneous scar. The patient had a complete response to preoperative RT. After MTB discussion, no further adjuvant treatments were provided. The patient did not show postoperative complications and was discharged on postoperative day 5. Neither relapse or systemic progression occurred in 24-months post-operative follow up. After the surgery the patient wore a shoulder brace for 15 days to avoid damage to the flap. Then a rehabilitation program consisting of 24 sessions (three times a week, lasting 1 h a session) was performed to improve the range of motion of the shoulder and motor performance of the shoulder girdle. No functional deficits were observed 6 months after surgery and at the 24-month follow up. Currently, after 2 years from surgery, at the clinical evaluation, the patient does not show differences in the flexion and abduction of the shoulder between right and left side (Fig. and ) and he confirms that he is leading a normal life without experiencing functional deficit or limitations in his daily life and his professional activities.
A 55-year-old woman presented with a 3-month history of right groin swelling, discomfort and impaired mobility. On examination, a palpable mass was noted both to the right of midline in the lower abdomen and in the right groin. Her family history is negative for malignancy of any kind.
