Giant benign nodular hidradenoma of the shoulder: A rare tumor in orthopedic practice.

Singhal V, Sharma SC, Anil J, Sachan PK, Harsh M, Singhal S, Raghuvanshi S - Int J Shoulder Surg (2010)

Bottom Line: It is generally found in the head, face, and upper extremity regions.Hence, its description in the orthopedic literature is extremely rare.We present a giant benign nodular hidradenoma presenting as painful restriction of the right shoulder joint in a 35-year-old male.

ABSTRACT
A clear cell hidradenoma is a rare dermal tumor, which is believed to originate from the apical portion of the sweat glands. The usual size reported is 5-30 mm. It is generally found in the head, face, and upper extremity regions. This lesion has not been reported to be large enough to impinge a joint range of motion. Hence, its description in the orthopedic literature is extremely rare. We present a giant benign nodular hidradenoma presenting as painful restriction of the right shoulder joint in a 35-year-old male.

Figure 0004: H and E stained section in ×40 magnification showing psammoma bodies in the lesion

Mentions: The lesion was well circumscribed and showed a fibrous capsule on one side and fibrofatty tissue on the other side. It consisted of nodules of various sizes separated with fibrous bands. Each nodule was partly solid and partly showing glandular or cystic spaces. The latter contained papillary structures. Cuboidal cells lined the glandular spaces and papillary structures with uniform overlapping pale staining nuclei. The spaces contained eosinophilic granular material. In between the glandular spaces and in the solid areas, the cells were either polyhedral or rounded having a clear cytoplasm and rounded nuclei or oval with elongated nuclei. Many psammoma bodies or large chunks of calcification were seen at many places. Mitotic figures were rare and there was no necrosis. The histopathological diagnosis of benign NH was made in view of the above-mentioned findings typical for this tumor [Figures 3 and 4]. No further immunohistochemistry tests were done as the pathologist reported adequate evidence of this lesion being benign.
