“…In the other two cases published the patients had recurrent UTIs [3,4]. The most common clinical presentation of adenocarcinoma of the appendix is with symptoms of acute appendicitis, since the cancer causes luminal blockage [13]. The average age is similar to those with adenocarcinoma of the colon, 55.1-62 years [1,14,15].…”

“…The incidence of primary appendiceal cancer other than carcinoid tumor is estimated to be <0.5% of all gastrointestinal neoplasms and 0.1–0.8% of appendectomy specimens [3, 5, 6]. Primary appendiceal adenocarcinoma is generally classified into two main types: cystic and colonic type.…”

“…Appendiceal tumors seldom show any specific symptoms and little is known about their specific findings on examination, thus it is difficult to preoperatively diagnose them. The preoperative detection rate of appendiceal tumors is low, ranging from 6.6 to 25%, and no sufficiently accurate diagnostic modalities have so far been developed [3]. Therefore, many malignant appendiceal tumors, including appendiceal adenocarcinoma, are diagnosed at an advanced stage, thus resulting in their poor prognosis compared to usual colon cancers [2, 4].…”

Primary appendiceal adenocarcinoma is an infrequent disease. This report presents a rare case of incidentally discovered carcinoma in situ of the appendix. A 35-year-old parturient female simultaneously underwent appendectomy and oophorectomy due to an ovarian abscess that adhered to the appendix during cesarean section. Although her excised appendix showed no apparent tumorous lesion, histopathological examination revealed carcinoma in situ in the excised appendix. She underwent additional right hemicolectomy a few days later due to the possibility of a positive surgical margin. Histopathological examination detected no malignant cells in the resected specimen. She was discharged without any complications and has since remained healthy. Appendiceal adenocarcinoma is generally considered to be difficult to diagnose during the early stage because it seldom shows any specific findings. This results in a poor prognosis. Histopathological examination is not always conducted for appendices resected during other surgery. However, the current study suggests that a careful routine histopathological examination of excised appendix, as well as careful preoperative examination and detailed intraperitoneal inspection during surgery, is indeed important to detect occult appendiceal tumors.

“…The preoperative detection rate of appendiceal tumors is low, ranging from 6.6 to 25%. So far, no sufficiently accurate diagnostic modalities have been developed [11]. Adenocarcinoma of the appendix is considered one of the most frequently perforating carcinoma of the entire gastrointestinal tract [12].…”

A 65 year-old female presented with a painful, swollen, red right thigh and the mild pain in the right abdomen without nausea, vomiting or diarrhoea that lasted for one week. Laboratory findings revealed elevated inflammatory markers. Computed tomography of the right thigh, abdomen and pelvis showed an abscess formation in the adductor muscles draining from the abscess that completely occupied the right retroperitoneum up to the diaphragm, dissecting downward through the inguinal canal. Appendix was enlarged with an appendicolith. Emergent exploratory laparotomy revealed a perforated appendix with psoas abscess. Pathohistological diagnosis revealed adenocarcinoma of the appendix. Thigh abscess is an uncommon condition with insidious clinical presentation. Therefore, early recognition and setting of the correct diagnosis enables adequate treatment avoiding additional complications and in some cases potential life-threatening conditions. When upper leg abscess is suspected or proven abdominal examination is mandatory.

Early Carcinoma of the Appendix Vermiformis

Abstract: It is difficult to preoperatively diagnose early carcinoma of the vermiform appendix because of its rarity and few specific clinical features. In the present study, we report a preoperatively diagnosed mucosal carcinoma of the vermiform appendix.
