Overview

Adenomatoid tumor is a rare benign mesothelial tumor affecting female and male genital tract (testicular adnexa). It generally presents in the genital tract, in regions such as the testis and epididymis.However, it also has been found in the pancreas.

Pathophysiology

  • Adenomatoid tumors are benign, solid extratesticular lesions that can originate from the epididymis, tunica vaginalis, or spermatic cord.[1][2][3]
  • They are the most common tumor of the epididymis.[4][5]
  • They occur more often in the lower pole than in the upper pole by a ratio of 4:1.[6][7][8]
  • Usually an incidental finding, adenomatoid tumors manifest as a painless scrotal mass, with the majority diagnosed in patients aged 20–50 years.[9][10][11]
  • They are typically unilateral and occur more frequently on the left side. When they grow noninvasively into the testicular parenchyma, they can simulate intratesticular disease.[12][13][14][15]

Gross pathology

  • 1 - 5 cm, well circumscribed solid tumor, adherent to testis / testicular adnexa
  • Cut surface may have small cystic spaces

Histopathology

  • No distinct growth pattern
  • Unencapsulated, cuboidal to flat cells forming cords that are either epithelial-like or form channels with dilated lumina simulating vessels
  • Cells have acidophilic cytoplasm with cytoplasmic vacuoles
  • Nuclei lack nucleoli
  • Mitoses and necrosis are usually absent
  • Intervening stroma may have smooth muscle and elastic fibers, desmoplastic quality and inflammatory cells
  • Rarely, tumor may extend into testicular parenchyma or even rarer, be totally inside the testis[5][13]
  • Patterns have been described but most tumors show a mixture of:[16][17][18][19][20]
    • Adenomatoid (tubular): glandular pattern with cytoplasmic vacuoles giving a signet ring appearance
    • Angiomatoid (canalicular): cells have a more endothelial appearance
    • Solid (plexiform): cells have a more epithelial appearance
    • Cystic (mixed): rare; tumor is in form of cystic spaces lined by cuboidal to flattened lining epithelium

Cytology

  • Smears are moderately cellular with sheets of monotonous round to oval cells showing indistinct cell borders and moderate to abundant pale cytoplasm with vacuolations [8][21]
  • Nuclei are eccentric in location but regular with inconspicuous nucleoli[22][3][15]

Immunostaining

  • Adenomatoid tumor stains positive for:[10]
    • Calretinin
    • Pan cytokeratins (EMA, AE1 / AE3, Cam5.2)
    • CK5 / 6
    • CK7 (variable, focal to diffuse)
  • Adenomatoid tumor stains negative for:
    • Vascular / endothelial markers (CD31, CD34)
    • CEA
    • HBME1
    • Factor VIII Ag
    • MOC31 / BerEP4
    • B72.3
    • CD15
    • Ulex europeus agglutinin I
    • Germ cell markers including:
      • OCT3 / 4
      • SOX2
      • AFP
      • PLAP
      • CD117
      • CD30
      • NANOG

Electron microscopy

  • Prominent microvilli
  • Desmosomes
  • Tonofilaments associated with dilated intercellular spaces

Causes

  • Mesothelial origin based on immunohistochemical features and ultrastructural studies [23]
  • Similar tumor in spermatic cord, ejaculatory duct, fallopian tube, uterus

Epidemiology and Demographics

  • 30% of testicular adnexal tumors, 73% of benign tumors of testicular adnexa in study of 314 tumors[24]
  • Usually 3rd to 5th decade; rare - 5 year old boy[25] and 70 year old man[26]

Risk Factors

  • Schimmelpenning syndrome is associated with the presence of multiple adenomatoid odontogenic tumors[27]

Natural History, Complications and Prognosis

  • Uniformly benign behavior, no reports of malignant transformation

Diagnosis

  • Diagnosis is suspected clinicoradiologically, confirmed histologically

History and Symptoms

Common sites of involvement

  • Adenomatoid tumor most commonly involves the following sites in male genital tract:[28][29][30][31][32][33][34]
    • Lower pole of epididymis
    • Testicular membranes including:
    • Spermatic cord (rarely)
    • Rete testis (rarely) [37]
    • Testicular parenchyma i.e. intratesticular localization (rarely)[11][13]
  • Extragenital areas are also rarely involved and may include:

Symptoms

  • Presents as solid, well circumscribed mass in scrotum, often associated with pain
  • Usually 1 - 5 cm, rarely larger[48]
  • Benign, even if it extends into testis

Laboratory findings

  • No specific laboratory finding; however, negative markers for germ cell tumor are helpful in excluding a germ cell malignancy

Ultrasound findings

  • On an ultrasound, they appear as a solid extratesticular mass with variable echogenicity.[49]
  • USG reveals a relatively hypo, iso to hyperechoic mass at lower pole of epididymis, not distorting the testis

MRI

  • Commonly, MRI demonstrates low signal intensity relative to the testicular parenchyma on T2-weighted images.
  • MRI can aid in determining the paratesticular origin of the lesion.
  • Adenomatoid tumors enhance after administration of gadolinium contrast material.

Treatment

  • Complete excision
  • Frozen section examination may prevent unnecessary radical orchiectomy[50][51]
  • Paratesticular tumors are rare tumors that are difficult to diagnose preoperatively and therefore, many patients are subjected to inguinal orchiectomy. However, radical orchiectomy can be avoided as the diagnosis of paratesticular tumor can be made on the basis of clinical suspicion, findings of tumor markers and radiological tests.

Differentiating Adenomatoid tumor from other diseases

  • Adenomatoid tumor must be differentiated from:
    • Malignant mesothelioma (HBME1+, mitoses and necrosis)
    • Metastatic adenocarcinoma (positive for one or more of CEA, PSA, MOC31 / BerEP4 and CD15 are useful)
    • Papillary cystadenoma of epididymis
