Clinical features of the patient. (a) An elongated-shaped, reddish-brown cutaneous lesion measuring 1.8 x 0.8 cm in the patient's right upper chest (arrow). (b) A heterogeneous, hyperechoic mass surrounded by a low-echogenic area on preoperative ultrasonography

Physical examination revealed an elongated-shaped, nontender, fluctuating cutaneous lesion with reddish-brown discoloration measuring 1.8 x 0.8 cm [Figure 1a]. Preoperative ultrasonography revealed a heterogeneous, hyperechoic mass surrounded by a low-echogenic area [Figure 1b].
Gross features of the lesion. (a) Illustration shows a solid tumour floating in an oval-shaped, serous-filled sac formed by thick fibrous tissue. (b) Resected specimens show a pear-shaped solid tumour with a lobulated appearance and sac-forming fibrous connective tissue

The gross features of the lesion revealed a small solid tumour floating in an oval-shaped, serous-filled sac formed by thick fibrous tissue [Figure 2].
Histopathological examination. (a) A solid tumour and dense fibrous connective tissue: the solid lesion revealed eosinophilic masses containing shadow cells with peripheral basaloid cells and the extrusion of eosinophilic aggregations at the focal area of the periphery (H and E, 40x). (b) Dense neutrophil infiltration with a few phagocytic macrophages within the fibrous connective tissue (H and E, 400x)

On histopathological examination, the specimens consisted of a solid tumour and dense fibrous connective tissue: the solid lesion revealed densely packed zones of eosinophilic masses containing shadow cells with peripheral basaloid cells and the extrusion of eosinophilic aggregations through the epithelial lining at the focal area of the periphery [Figure 3a]. Within the fibrous connective tissue, dense neutrophil infiltration with a few phagocytic macrophages was observed [Figure 3b].
