Abstract
Scleros ng polycyst c adenos s (SPA) s a rare ben gn sal vary gland les on. Dysgenet c polycyst c d sease (DPD), wh ch s a h stolog cally s m lar les on, may cause a latt ce-l ke gross appearance w th b lateral enlargement of the ent re sal vary glands. In th s report, we present a case of SPA n the r ght parot d and coex stent DPD nvolv ng the both parot d.

Introduct on
Scleros ng polycyst c adenos s (SPA) s a rare ben gn sal vary gland les on wh ch s character zed by morpholog cal s m lar ty to f brocyst c changes, scleros ng adenos s, and ntraductal ep thel al prol ferat ons of the breast. SPA occurs over a w de age spectrum and s mostly un focal.[1],[2] The les ons are well c rcumscr bed and are composed of densely sclerot c lobules w th prom nent cyst c, metaplast c, and hyperplast c changes n the ductal and ac nar elements. The d fferent al d agnos s of SPA ncludes a var ety of non-neoplast c and neoplast c sal vary gland les ons also nclud ng dysgenet c polycyst c d sease (DPD).[3] The presence of cyst cally d lated ducts and apocr ne metaplas a are the most frequent shared features.
DPD s a congen tal d sease, frequently seen n females and s character zed by mult ple ep thel al-l ned cyst c spaces ar s ng from ac n and ntercalated ducts.[4],[5] In th s paper, we present a coex stence of SPA of the parot d w th b lateral DPD wh ch were not documented prev ously.
Case Report
A 35-year-old woman appl ed to hosp tal w th a slowly grow ng, pa nless, hard parot d mass, not ced recently w thout other mean ngful cl n cal symptoms. Cl n cal h story revealed that she had been succesfully treated for acute lymphoblast c leukem a w th chemotheraphy and rad otheraphy to the head of poss ble bra n nvolvement. Then total thyro dectomy was performed for thyro d pap llary carc noma and th s was followed by rad oact ve od ne treatment.
Ultrasonograph c and magnet c resonance mag ng [F gure 1] exam nat ons revealed a sol d, hypoecho c les on 2.3 cm n largest d ameter w th n the deep poster or part of the rregular look ng r ght parot d gland. In magnet c resonance mag ng small cyst c changes and calc f ed dens t es w th n both enlarged parot d glands [F gure 1]. Add t onally, small
m crocalc f cat ons were dent f ed n the r ght and left parot d parenchyma. A r ght total parot dectomy was performed.{F gure 1}
Grossly, the parot dectomy spec men measured 6 × 3 × 2.5 cm n s ze. The cut surface showed a f rm, well demarcated nodular les on 2.3 cm n t's largest d ameter w th a rubber cons stency. The sal vary gland around the mass had a sponge l ke parenchyma and latt ce-l ke appearance.
M croscop cally; the sol tary les on was a well encapsulated nodule cons st ng of prol ferat ng ducts n a sclerot c collagenous stroma [F gure 2]. The duct prol ferat ons were composed of scleros ng adenos s-l ke closely packed areas, cr br form structures, sol d slands, cyst c changes and apocr ne metaplas a. It was d agnosed as a representat ve example of SPA. H stolog cally, s m lar to gross apparence the sal vary gland parenchyma outs de the les on demonstrated mult ple lobules of cyst c spaces n vary ng s ze w th a latt ce-l ke appearance. The cyst c changes nvolved the ac n more frequently than the ducts and were l ned by cubo dal or flattened ep thel al cells w th vacuolated cytoplasm rem n scent of lactat onal change of the breast. Cyst c ducts of the DPD commun cates w th the normal lobular structures of the sal vary glands. The lum na of these cysts conta ned pale eos noph l c secret on, globular dens spherules w th concentr c lamellat on, m neral zat on, large s alol ths, and macrophages [F gure 3]. Th s coex stent w despread cyst c change was cons stent w th a d agnos s of DPD. Abdom nal MRI also revealed splen c subcapsular cysts of vary ng s ze.{F gure 2}{F gure 3}
Immunoh stochem cally there was d ffuse CK 7 mmunoreact v ty n the ductal ep thel al cells and smooth muscle act n and p63 pos t v t es n the myoep thel al layer around the ducts wh ch were h ghl ghted the presence of b phas c pattern. Weak estrogen receptor pos t v ty was found w th n the prol ferat ng ducts and K -67 mmunoreact v ty was less than 2%.
D scuss on
SPA was grouped under the nonneoplast c ep thel al les ons of sal vary glands n the 2017 WHO class f cat on.[6] However, the presence of an un nterrupted th ck capsule, a centr fugal growth pattern and a totally d fferent h stolog cal pattern from the surround ng t ssue seen n the present SPA case may support the poss b l ty of neoplas a.[7] Rarely, SPA may be

assoc ated w th other sal vary gland les ons, though the coex stence of SPA and DPD as n our case has not been reported prev ously. In the present case, morpholog cally, t was not d ff cult to d st ngu sh the local zed SPA from DPD wh ch nvolved ent rely b lateral sal vary glands.
H stolog cal features of DPD may resemble those of polycyst c cond t ons affect ng the other organs. However, there s no report about the assoc at on of DPD nvolv ng other organs except for a s multaneous mult ple, major, and m nor sal vary gland nvolvement.[8]
Except splen c cysts n the present case, there s no reported assoc at on.[9] Immunoh stochem cal sta n ng results n our case showed a dual ep thel al and myoep thel al d fferent at on n SPA and DPA, cons stent w th the prev ous reports.[2] Th s f nd ng s s m lar to the prol ferat ve breast les ons.
The prev ous chemotheraphy and rad otheraph es may be contr but ng factors for the development of SPA n the present case. The coex stence of SPA and DPD n th s report may well suggest that the w despread cyst c changes n the both sal vary gland prov ded a ground for the format on of SPA. SPA cases were usually treated w th exc s on of the sal vary gland and the recurence rates were low.[10] We bel eve that the management of the DPD should be ta lored accord ng to the cl n cal symptoms. The cyst c les ons of the left parot d w ll be followed-up n the present case.
