Reporte del primer caso de cistoadenoma papilar de epidídimo en Colombia, Hospital Universitario de Santander / Report of the first case of papillary cystadenoma of the epididymis in Colombia

Resumen La presencia de una masa en la región escrotal comprende un amplio espectro de patologías, unas con mayor urgencia para el manejo que otras, dado el riesgo asociado de pérdida testicular o desarrollo de cáncer. Dentro de las posibilidades diagnósticas se encuentran las neoplasias, destacando las originadas en el epidídimo, con un 75% de casos de etiología benigna, correspondiendo un 9% al cistoadenoma papilar de epidídimo que sobresale por su baja frecuencia dado que en la literatura mundial existen aproximadamente 70 reportes publicados con escasos provenientes de literatura médica en castellano, en los que se incluye el presente caso expuesto en el que se confirma histopatológicamente un cistoadenoma papilar de epidídimo y se presenta una revisión del tema acerca del enfoque de un paciente con masa escrotal. Asimismo se resalta el hecho de que esta lesión puede asociarse con la enfermedad de Von Hippel Lindau, sobre todo en presentaciones bilaterales. MÉD.UIS. 2020;33(2):95-100.

Abstract The presence of a mass in the scrotal region comprises a wide spectrum of pathologies, some with greater urgency for management than others, given the associated risk of testicular loss or cancer development. Among the diagnostic possibilities are the neoplasms, highlighting those originating in the epididymis, with 75% of cases of benign etiology, 9% corresponding to the papillary cystadenoma of the epididymis that stands out for its low frequency given that in the world literature there are approximately 70 published reports with few from medical literature in Spanish, which include the present case presented in which a papillary cystadenoma of the epididymis is confirmed histopathologically and a review of the topic about the approach of a patient with scrotal mass is presented. Also the fact that this lesion can be associated with von Hippel Lindau disease, especially in bilateral presentations is highlighted. MÉD.UIS. 2020;33(2):95-100.

Nevo de Jadassohn asociado a siringocistoadenoma papilífero / Associated Jadessohn's nevus syringocistoadenoma papilífero

El siringocistoadenoma papilífero (SCAP) es un tumor anexial benigno, poco frecuente, que deriva de las glándulas sudoríparas écrinas o apócrinas. Afecta a ambos sexos por igual, se observa desde el nacimiento o en la primera infancia. Se manifiesta como una placa solitaria alopécica en cuero cabelludo, o como pápulas de color piel en rostro y cuello. En el 40% de los casos se asocia a un nevo sebáceo preexistente. El tratamiento de elección es la extirpación quirúrgica. Se presenta un varón de 14 años, con un nevo de Jadassohn presente desde el nacimiento, que desarrolló años posteriores un SCAP. Palabras clave Nevo de Jadassohn, nevo sebáceo, siringocistoadenoma papilífero, tumor anexial benigno.

The syringocystadenoma papilliferum (SCAP) is an adnexal benign tumor, uncommon, which derives from the eccrine or apocrine sebaceous glands. It affects both sexes equally, it occurs most frequently from birth or early childhood. It manifests clinically as a solitary raised plate located mainly on scalp, or as papules in face, and neck. In 40% of the cases it is associated with a pre-existing sebaceous nevus. The treatment of choice is surgery. We present a 14 year old male, with a history of a nevus of Jadassohn present from birth, that years later developed a SCAP

Cistoadenoma papilar oncocítico de glándula parótida: caso clínico / Papillary oncocytic cystoadenoma of the parotid gland: case report

RESUMEN El cistoadenoma es un tumor epitelial benigno raro de glándulas salivales, de crecimiento lento y asintomático, que forma grandes masas uni o multiloculares con desarrollo papilar intraluminal. Si bien es más frecuente en glándulas salivales menores, se ha destacado lo inusual de la lesión en glándulas salivales mayores. Se presenta el caso de una mujer de 60 años, quien consultó por una masa indolora, blanda y de consistencia quistica en glándula parótida derecha, de crecimiento lento y progresivo. Su evolución fue de varios meses con piel de la zona intacta. Se realizó parotidectomia superficial. El examen histopatológico demostró cistoadenoma papilar oncocitico, tumor que ha sido destacado por su infrecuencia, y con una manifestación en parótida sumamente rara y de variados patrones histológicos. Su reconocimiento es trascendente para el profesional en casos como el que se presenta, pues su diagnóstico diferencial incluye lesiones con aspecto clínico similar y en algunos casos comportamiento agresivo.

ABSTRACT The cystadenoma is a rare benign epithelial tumor of salivary glands, characterized by slow growing and asymptomatic presentation, forming large uni or multilocular masses with intraluminal papillary development. Although it is more frequent in minor salivary glands, it has been emphasized the unusual of the major salivary glands affection. We present the case of a 60-year-old woman consulting for a painless, soft mass with cystic consistency in the right parotid gland, slow and progressive growing. The tumor evolved for several months keeping the skin of the area intact. A superficial parotidectomy was performed. Histopathological examination demonstrated a papillary oncocytic cystadenoma, a tumor that has been noted for its low frequency, and with extremely rare parotid manifestation and varied histological patterns. Its recognition is relevant for the professional in cases such as the one presented, since its differential diagnosis includes lesions with similar clinical appearance and in some cases aggressive behavior.

A Case of Mucinous Cystadenoma Mimicking Mucoepidermoid Carcinoma in Parotid Gland / 대한이비인후과학회지

Cystadenoma rarely arises in the parotid gland. It grows slowly without pain. Histopathologically, it is subdivided into papillary cystadenoma and mucinous cystadenoma. Mucinous cystadenoma arising from the salivary gland is a very rare benign tumor. A 25-year-old female patient visited our hospital with a left infra-auricular mass. Computed tomography scan showed a 3.1x2.3 cm size heterogeneous lesion with an irregular margin in the left parotid gland. Sono guided gun biopsy was performed to reveal fibrous tissue with atypical epithelial cell with mucin. Suspecting mucoepidermoid carcinoma, partial parotidectomy was performed for treatment and diagnosis. Histopathologic exam revealed mucinous cystadenoma. Cystadenoma of salivary gland has no distinct clinical feature, and is difficult to differentiate clinically from other salivary gland tumors as well as its malignancy. Thus, the possibility of malignancy must be considered for differential diagnosis.

Papillary cystadenoma of the epididymis: a report of 2 cases and review of the literature / 中华男科学杂志

<p><b>OBJECTIVE</b>To study the clinicopathological characteristics of papillary cystadenoma of the epididymis.</p><p><b>METHODS</b>Using routine pathology and immunohistochemistry, we observed the surgically obtained samples from 2 cases of papillary cystadenoma of the epididymis, analyzed their pathological features and clinical presentations, and reviewed the related literature.</p><p><b>RESULTS</b>The 2 patients were both adult males. The tumors typically manifested as painless swelling in the epididymis, with occasionally dull pain and tenesmus in 1 of the cases. Pathologically, the lesions exhibited three morphological features, i. e., dilated ducts and small cysts surrounded by fibrous connective tissue, adenoid papillary hyperplasia into the cysts embraced by fibrovascular stroma, and acidophil substance present in the cysts. Immunohistochemistry showed that the tumors were strongly positive for CK8/18, CK7, and EMA, but negative for CK20, CEA, MC, Calretenin, P53, P63, SMA, VHL, and CD10, with the positive rate of Ki-67 <1%. Follow-up visits revealed good prognosis in both cases.</p><p><b>CONCLUSION</b>Papillary cystadenoma of the epididymis is a rare benign tumor in the male urogenital system, which may be accompanied by the VHL syndrome. Surgery is the first choice for its treatment.</p>

Mucinous cystadenoma of the liver with ovarian-like stroma: the need for complete resection / 대한외과학회지

Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However, it remains difficult to differentiate cystadenoma from cystadenocarcinoma for multiseptated cystic hepatic lesions with papillary projection on computed tomography (CT) and magnetic resonance imaging (MRI). Here we report the case of a 47-year-old woman with several months of postprandial discomfort and abdominal fullness. CT and MRI revealed multiseptated cystic lesions with papillary excrescences. A left hemihepatectomy was performed. Histology showed a benign mucinous cystic tumor with ovarian-like stroma.

75-year old man complaining of flank pain and obstructive urinary symptoms: a case report

Benign renal cystic adenoma with out malignant features is a very rare entity. A 75 year old male with obstructive Lower tract symptoms and vague flank pain was admitted and planned for nephrectomy of non functional kidney-due to long term nephrolithiasis-intra operative finding was a cystic hydronephrotic kidney filled by thick mucous secretions which turned out to be a cyst adenoma of kidney with no malignant features

Correlación entre los hallazgos del ultrasonido doppler pélvico-trasvaginal: con la anatomía patológica: en tumores de ovario / Correlation between transvaginal color doppler and histologic diagnosis: in ovarian tumors

Correlacionar los hallazgos del ultrasonido doppler pélvico-transvaginal con el congelado y la biopsia definitiva en pacientes con tumores de ovario que acuden al Hospital General del Este "Dr. Domingo Luciani" octubre 2007-2008. Se incluyeron 33 pacientes entre 18-70 años con tumores de ovario. Se les realizó ultrasonido Doppler pélvico-transveginal previa intervención quirúrgica indicada para cada patología. Se les realizó corte congelado y biopsia definitiva y éstos se compararon posteriormente con los resultados del ultrasonido. Un 66% fueron tumores benignos, el cistoadenoma seroso fue el más frecuente (36.3%), 33.3% fueron malignos, con 27.2% para adenocarcinoma. La sensibilidad del sistema de puntuación para masas ováricas fue del 100% y 95% de especificidad. El índice de Resistencia (IR), Indice de Pulsatilidad (IP) y la Velocidad Pico Sistólica (VPS), presentaron sensibilidad de 89%, 100% y 90% con especificidad de 95%, 85% y 91% respectivamente. El corte congelado presentó concordancia en el 100% de los casos con la biopsia definitiva. El ultrasonido pélvico transvaginal con efecto Doppler resultó tener alta sensibilidad y especificidad para la diferenciación de tumores benignos y malignos de ovario.

Frozen section and definitive biopsy were 100% concordant. Pelvic-transvaginal Doppler in our study have high sensitivity and specifity in ovarian's tumors.

A case of primary clear cell carcinoma of broad ligament / 대한산부인과학회지

Primary broad ligament tumors are a rare entity, although secondary involvement of broad ligament by a malignancy arising elsewhrere in the abdomen/pelvis is common. Among the primary broad ligament tumors, leiomyoma is the most frequent histopathological type followed by serous papillary cystadenoma of borderline malignancy. Primary sarcomas and high-grade carcinomas have been extremely rarely reported. Because of the rarity of disease, its treatment policy, follow-up strategy and prognosis are yet to be established and it is managed as an ovarian malignancy. We had experienced a case of clear cell adenocarcinoma arising from broad ligament and report this case with a brief review of literature.

Cystadenoma: a rare tumor originated in minor salivary gland / Cistadenoma: um tumor raro em glândula salivar menor

Cystadenoma of salivary glands is an uncommon benign neoplasm that presents intraluminal papillary projections. The authors describe one case of cystadenoma located in the buccal mucosa and highlight its histomorphological features and differential diagnosis.

O cistadenoma de glândula salivar é uma neoplasia benigna incomum, que exibe projeções papilíferas intraluminais. Os autores descrevem um caso de cistadenoma localizado na mucosa jugal, discutindo os aspectos histomorfológicos e o diagnóstico diferencial desse tumor.

Clear Cell Papillary Cystadenoma of the Epididymis Associated with Multiple Renal and Pancreatic Cysts / 대한남성과학회지

Papillary cystadenoma of the epididymis is a rare benign tumor that accounts for only 5% of all epididymal tumors. A case of epididymal cystadenoma was presented in a 25 year old man. The patient was hospitalized initially because of infertility and bilateral painless palpable scrotal masses. He had multiple renal cysts and pancreatic cysts. He had no renal, adrenal, cerebellar or retinal lesion as cardinal manifestation of the Von Hippel-Lindau Syndrome (VHL). The VHL gene mutation in this case was not identified. For evaluation and management, we planned left epididymovasostomy and left testicular biopsy. However, due to a cystic change on the left epididymis and left tunica albuginea, we instead performed a left partial epididymectomy for the cystic lesion, excision of the cystic mass from the left tunica albuginea, and diagnostic left testicular biopsy. The pathologic evaluation revealed a papillary cystadenoma of the epididymis and tunica albuginea, but with normal spermatogenesis.

A Serous Papillary Cystadenoma of Borderline Malignancy in Testis / 대한남성과학회지

Serous papillary cystadenomas arising in testis have been rarely reported, and they often resemble ovarian serous tumors of borderline malignancy. Herein, we report a case of a serous papillary cystadenoma of the testis in a 59 year old man. Based on a clinical diagnosis of left testicular tumor, a left radical orchiectomy was performed. The pathologic evaluation revealed a serous papillary cystadenoma of borderline malignancy in the testis.

Solid and cystic epithelial neoplasm of pancreas with metastasis: a report of a highly unusual case

Solid and cystic papillary epithelial neoplasms of the pancreas are uncommon tumors occurring predominantly in young women. These tumors have excellent prognosis and after complete surgical resection, more that 95% patients are cured. Occasionally, they invade the surrounding pancreatic parenchyma. These tumors can recur even many years after resection, so long term follow up is essential. Very few cases metastasize. We present a case of a middle aged woman with metastases to liver and omentum

Spleen-preserving distal pancreatectomy following neoadjuvant chemotherapy for papillary solid and cystic neoplasm of pancreas.

Papillary solid and cystic neoplasm (PSCN) is a rare neoplasm of the pancreas with low-grade malignant potential and favorable prognosis. We report an 18-year-old girl with PSCN presenting with advanced disease. The tumor regressed with six cycles of gemcitabine and cisplantin-based neoadjuvant chemotherapy; spleen-preserving distal pancreatectomy was then done. She is disease-free at 13 months' follow-up.

Aspiration cytology, histology and hormone status in solid and cystic papillary tumor of pancreas--report of three cases.

Solid and cystic papillary tumor of pancreas (SCPT) are rare tumors. Of the well described cases 95% have occurred in women of reproductive age, suggesting a role of hormonal factors in the pathogenesis of this tumor. Only few studies evaluating estrogen and progesterone receptor status have found it to be positive. Cytohistocorrelation and immunohistochemistry for estrogen (ER) and progesterone (PR) receptors of three such cases are reported here. All three were diagnosed by fine needle aspiration cytology (FNAC) and showed cytoplasmic positivity for ER and PR receptors. May-Grunwald Giemsa, Papanicolaou and hematoxylin and eosin stained slides were evaluated for cytology and histopathology. Unstained methanol fixed slides were used for immunohistochemistry. The cytoplasmic staining of ER and PR receptors cannot be underestimated, as shown by Carbone A et al which represents ERII receptors. This study confirms the presence of ER and PR receptors in these tumors and highlights the already established cytological features.

Fine needle aspiration cytology of extrapancreatic solid-cystic tumour of pancreas: a case report.

Fine needle aspiration cytological features of solid-cystic tumor (SCT) of pancreas occurring adjacent to pancreas is reported for its rare occurrence. On cytology, diagnosis of paraganglioma was suggested. After histologic diagnosis of SCT, cytology was reviewed that showed typical features of SCT. On cytology, diagnostic problem in SCT occurring outside pancreas is illustrated.

Papillary cystadenoma of the epididymis accompanied by testicular atrophy: one case report / 中华男科学杂志

Papillary cystadenoma of the epididymis is a rare benign tumor, accounting for only 4 per cent of all epididymal tumors. Histologically, it can be confused with metastatic renal cell carcinoma. This extremely rare lesion may occur sporadically or as a manifestation of von Hippel-Lindau(VHL) disease. The present paper reported a case of papillary cystadenoma accompanied by testicular atrophy with no signs of VHL syndrome or infertility. To date, no similar case was reported in the literature. The tumor measured 5.0 cm x 4.0 cm x 4.0 cm and was located in the right epididymis. Histopathologic examination of a surgically removed specimen indicated a primary papillary cystadenoma. Histomorphologically, these tumors are characterized by cysts with colloid-like contents and papillary formations of light epithelium. Since metastatic renal cell carcinoma may be histologically similar to papillary cystadenoma, the importance of long-term urologic follow-up for possible presentation of renal cell carcinoma is discussed.
