Orbital apocrine hidrocystoma with immunohistochemical confirmation

Hidrocistoma apócrino orbitário com confirmação imunohistoquímica

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

The authors report the first case in Brazilian literature of orbital apocrine hidrocystoma with immunohistochemistry confirmation. The tumor had been growing slowly and progressively, there was no history of impaired vision, diplopia, watering, discharge, or prior trauma. There was no proptosis and extraocular mobility was normal. The radiologic study by orbital computerized tomography revealed an extraconal nodule, with partially defined limits, with cystic and solid areas in the superomedial right orbit. An anterior orbitotomy, with full excision of the tumor was performed. A histopathology examination revealed apocrine hidrocystoma and immunohistochemistry confirmed the diagnosis. After surgery, the patient had total remission of symptoms.

Immunohistochemical markers	Function summary
Citokeratin 7 (CK7).	Type II keratin of simple non-keratinizing epithelia. The cytokeratin 7 is a positive marker in glandular epithelium.
Gross Cystic Disease Fluid Protein 15) (GCDFP15)	Also called BRST2, prolactin-induced protein (PIP). It is an excellent marker of apocrine differentiation. It is a glycoprotein originally isolated in human breast gross cystic fluid.
S100 Protein (S100)	Acidic protein, 100% Soluble in ammonium sulfate at neutral pH (derivation of name). It is present in eccrine glands inner layer. Common marker of neural tissue / lesions and melanoma.
Smooth Muscle Actin (SMA)	Identify myoepithelial cells in normal, neoplastic or diseased breast, salivary glands or sweat glands.
