CASE 835: CYSTIC LYMPHANGIOMA in MASSETER SPACE, Dr PHAN THANH HẢI, Dr PHẠM THỊ THANH XUÂN, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

A 28 year-old girl with a doubtful mass at her left face which only appears in prone position for 20 years. That mass is yet diagnosed from many clinics since 8 years old. 



Fig 1: Swollen left cheek and unclear the left nasolabial groove were in bending and sitting position.



Fig 2: The left cheek was not swollen and the existence of the left nasolabial groove before bending of the head.

Face ultrasound detected nothing in supine position. But in bending down her head the left nasolabial groove disappears. Then the left cheek was swollen and ultrasound revealed a #35x15mm echoic cystic lesion into the left masseter space. 



MSCT non CA confirmed the cystic lymphangioma in the left masseter space in two positions : supine  (upper line) and prone (lower line)


The girl was pleased with the explanations but she denies any procedure of FNAC or puncture for sclerotherapy that may causing any scar of her face.

The cystic lymphangioma in the masseter space is a rare entity. The story which we learned about of the case is paid attention at something doubtful of the patient’ complaint and trying to find it out. In that case it only was the appropriate position to detect a ghost mass on the left cheek of the nice girl.

CASE 830: PANCREATIC CANCER and a REVIEW of the PERITONEAL CARCINOMATOSIS, Dr PHAN THANH HẢI, Dr TRẦN NGÂN CHÂU, MEDIC MEDICAL CENTER, HCMC, VIETNAM


A 58 year-old man with epigastric pain and flatulence for one month.



Ultrasound detected a # 21x27mm hypoechoic tumor of the pancreatic body and peritoneal carcinomatosis [PC]: a large amount # 4 liters of malignant ascites, metastatic lymph nodes and peritoneal cake.



Lab data showed increased CA 19-9 : 807 U/mL and CA 125: 95.7U/mL


MSCT confirmed the peritoneal carcinomatosis.

Surgery was done for the peritoneal node biopsy. The result was an adenocarcinoma grade 2 metastasis with the pancreatic origin.

Surgical report noted many  # 10mm nodes seeding on the peritoneum that made retractile the  epiploon and the mesentery. There was a #80 mm hard mass seemed to be the primary tumor at the mesenteric root of the transverse colon.




Histoimmunologic staining:CK7. CA 19-9 (+), CK 20 (+) localized, CDX2,  SATB2 (-). That were in correlation to adenocarcinoma grad 2 metastase to the peritoneum with the origin of the pancreas.

DISCUSSION :

Ultrasound detects easily the PC but difficultely finds out the origin of the PC.

There were 3 published cases of extraovarian primary PC,

2 published cases of malignant mesothelioma,

1 published case of mucinous carcinoma (unknown the origin),

In total, 5 cases of not having the origin, 1 case of unknown the origin. (pls. view cases 128, 164, 298, 332, 448).
