A Remarkably Rare Position of a Cutaneous Ciliated Cyst in a 16 Month-old Female: A Case Report.

Objective: The aim of the work was to show a Cutaneous Ciliated Cyst (CCC) in an unusual location in a 16-month-old girl.

Case report: We present the case of a 16-month otherwise healthy girl presented to our hospital, with a report of a palpable mass in the left suprascapular region. Physical examination revealed a soft-textured, fluctuating, mobile and painless entity, with no further indications of local inflammation. The mass was totally excised, under general anesthesia, for both diagnostic and therapeutic purposes. According to the histopathological findings, the cystic lesion was covered by a pseudostratified ciliary epithelium, resembling the epithelium of a normal fallopian tube, surrounded by a smooth muscle layer. Immunohistochemical studies identified the cyst epithelium as having cytokeratin (CKAE1/AE3) expression, despite the negative immunostaining findings on Estrogen and Progesterone Receptors.

Conclusion: Our case report concerns a CCC in an unusual position, in the suprascapular area. After a thorough review of the international literature, we concluded that this is the second published case regarding this specific location. To our knowledge our patient is the youngest ever diagnosed with CCC.
