Dermoid cyst of the pancreas: presentation and management.
World J Surg Oncol. 2007
Aug 3;5:85.
BACKGROUND: Dermoid cyst of the pancreas is a benign,
well-differentiated, extremely rare germ cell neoplasm. Published
data indicate that differential diagnosis of cystic lesions of the
pancreas is challenging and although ultrasonography, computed
tomography and magnetic resonance may be useful, radiological
findings are often inconclusive and the diagnosis is intraoperative.
We report a case of a dermoid cyst of the tail of the pancreas
intraoperatively diagnosed and successfully treated with left
pancreatectomy. Further, characteristics, preoperative detection and
differential diagnosis of this rare pathology are also discussed.
CASE PRESENTATION: This report documents the findings of a
64-year-old male presenting with a well defined echogenic pancreatic
mass on ultrasonography. Computerized Tomography (CT) showed a 5 cm
cystic tumor arising from pancreatic tail and Magnetic Resonance
Imaging (MRI) suggested a tumor extension to the middle side of the
stomach without defined margins. A left pancreatectomy was
performed. On surgical specimen, histological evaluation revealed a
dermoid cyst of the tail of the pancreas measuring 8.5 x 3.0 cm.
CONCLUSION: Given the benign nature of the dermoid cyst, surgical
resection most likely represents the definitive treatment and cure.
In addition, resection is indicated in consideration of the
difficulty in diagnosing dermoid cyst preoperatively. However,
endoscopic ultrasound and fine needle aspiration cytology have
recently been shown to be effective, safe, reliable and cost-saving
preoperative diagnostic tools. Therefore, until more cases of
dermoid cyst are identified to further elucidate its natural history
and improve the reliability of the preoperative diagnostic tools,
surgical resection should be considered the standard therapy in
order to exclude malignancy.
Cystic teratoma of the pancreas: presentation, evaluation and
management.JOP.
2006 Nov 10;7(6):643-6.
CONTEXT:
Congenital cystic lesions of the pancreas are rare findings.
Furthermore, a dermoid cyst of the pancreas is exceptionally
uncommon. A review of the world literature shows 18 documented
cases. The pre-operative evaluation of this lesion is rather
questionable, with definitive diagnosis taking place
intra-operatively. CASE REPORT: A 52-year-old male with a
symptomatic, 3-cm cystic-type mass in the pancreas. CONCLUSIONS:
From our case presentation and review of the world literature, we
hope to establish an increased awareness in the diagnostic
evaluation of these patients.

of the pancreas: a rare cystic neoplasm.

Dermoid
cysts of the pancreas, also called cystic teratomas, are a rare
entity and are included in the group of neoplasms with a germ cell
origin. Only twelve cases have been described in the world
literature. The symptomatology is due to tumor compression of the
neighboring tissues. Ultrasonography and computed tomography may be
helpful, but there are no pathognomonic data for their preoperative
recognition. The differential diagnosis should include all other
cystic tumors of the pancreas. Complete surgical removal is
mandatory. We describe the diagnostic and surgical procedures in a
74 year-old man with a pre-operatively unsuspected dermoid cyst. We
review the previously published cases and emphasize the appropriate
therapeutical management.
Fine-needle
aspiration of dermoid cyst of the pancreas: a case report.
Diagn Cytopathol. 1993;9(1):66-9.
A 53-yr-old
woman presented with a left upper quadrant abdominal mass attached
to the body of the pancreas. Fine-needle aspiration (FNA) yielded
cyst fluid containing numerous benign, mature squamous cells,
keratin debris, and inflammatory cells. The diagnosis of dermoid
cyst was subsequently rendered on the resected specimen. The
cytologic and histologic features are presented. FNA cytology proves
to be a valuable diagnostic adjunct in the preoperative evaluation
of a patient with dermoid cyst of the pancreas.

teratomas of the pancreas.
Arch Surg. 1990;125(9):1215-8.
Cystic
teratomas of the pancreas constitute an extremely rare entity with
only nine cases, to our knowledge, described in the world
literature. Symptoms are usually due to the compressive effects of
the tumor on the neighboring organs. They should be considered in
the differential diagnosis of slow-growing benign pancreatic cysts.
We describe a 25-year-old woman with a pancreatic teratoma who was
operated on in 1976 with the diagnosis of calcified pancreatic cyst.
The diagnostic and surgical procedures are described, as well as a
14-year follow-up. The previously published cases are reviewed and
the differential diagnosis is discussed. Early diagnosis and the
need for total tumor resection are emphasized.

of the pancreas. Case report and review of the literature.

During
an annual check-up in a 46 year-old man, a round mass was discovered
in the left hypochondrium upon abdominal ultrasonography. Computed
tomographic scan located the mass at the upper border of the body of
the pancreas, suggesting an expansive process. Left pancreatectomy
was performed, leading to the discovery of a dermoid cyst. This cyst
was apparently part of the pancreatic parenchyma. Only 11 cases of
dermoid cysts of the pancreas have been reported between 1918 and
1977. Elective enucleation of the cyst is thought to be adequate
surgical treatment.
