RESUMEN
The patient was a 48-year-old woman. At the time of consultation, a hard mass of 30 mm in size was palpated in area A of the right breast, and a firm mass of about 10 mm was seen in the umbilical region. Histological diagnosis of the breast mass was invasive ductal carcinoma. PET-CT scan showed accumulation in the right breast, as well as suspicion of umbilical metastasis and peritoneal dissemination, uterine mass, and left ovarian cancer. Since this is an atypical metastatic site for invasive ductal carcinoma of the breast, and the possibility of peritoneal dissemination due to gynecological cancer complications cannot be ruled out, resection of the umbilical mass and laparoscopy was performed. The review laparoscopy revealed no evidence of primary cancer in the uterine body or left ovary, and a white nodular lesion of suspected seeding in the peritoneum around the left ovary. The histology and immunostaining results of the umbilical mass and left peri-ovarian nodule both showed glandular luminal structures similar to those of the primary breast cancer, and the left peri-ovarian nodule was ER positive, GATA3 positive, and PAX8 negative, leading to the diagnosis of umbilical metastasis and peritoneal seeding derived from breast cancer. Umbilical metastasis is often referred to as Sister Mary Joseph's nodule in the case of visceral malignancies and is often associated with peritoneal dissemination and is often caused by invasive metastasis of peritoneal dissemination lesions on the dorsal side of the umbilical region. In this case, histological examination of the umbilical specimen showed no disseminated lesion on the peritoneal side, so it was not considered to be an invasive metastasis due to peritoneal dissemination.

Prognosis of pancreatic cancer is extremely poor due to recurrence in the early postoperative period. However, there are some reports that the prognosis for lung recurrence alone is relatively better than that of others. In this study, we report the cases of lung recurrence alone after radical resection of pancreatic cancer performed at our hospital. Among 255 cases of radical resection of pancreatic cancer performed at our hospital between July 2010 and August 2021, 6 cases in which the initial recurrence site of recurrence was lung alone were included in the study. The median age of the patients was 72 years (62-82), and there were 5 males and 1 female. Four patients had undergone pancreaticoduodenectomy and 2 patients underwent distal pancreatectomy. Four patients received adjuvant chemotherapy, 3 with S-1 and 1 with GEM. No patients underwent surgical resection for recurrence of lung metastasis, and all patients were treated with chemotherapy. The median time to recurrence was 351 days. As initial therapy after recurrence, 3 patients received GEM plus nab-PTX combination therapy and 3 patients received S-1. The median overall survival after recurrence was 1,979 days, and the 1-year and 3-year overall survival rates after recurrence were 100% and 100%, respectively. The prognosis of patients with recurrence of lung metastasis after surgery for pancreatic cancer at our hospital was similarly good as the previous reports.

Para-aortic lymphadenectomy in gastric cancer surgery is a highly difficult surgical technique. In our hospital, we introduced robotic surgery in anticipation of the minimal invasiveness and advanced operability. We use a tunneling approach that progresses from the Treitz ligament to the peri-aorta. The transverse mesocolon is expanded with a tissue grasping clip, and the retroperitoneum is incised from the side of the Treitz ligament to approach the abdominal aorta and inferior vena cava. The No.16b1 and No.16a2 latero lymph nodes can be dissected with a good visual field. When it is judged that the visual field development of the No.16a2 inter-lymph nodes is poor, Kocher's operation is added. Since 2016, 18 patients have undergone para-aortic lymphadenectomy, 3 of whom underwent robotic surgery in our hospital. R0 resection was performed in all the cases, and 22.5 lymph nodes were dissected as No.16 lymph nodes(20.0 in all the cases included laparotomy). Although only a small number of patients were examined, robot-assisted para-aortic lymphadenectomy was considered safe.

A 75-year-old female, at her initial presentation, the tumor occupied her entire right breast, with a foul-smelling exudate. A biopsy revealed ER-positive, HER2-negative breast cancer, and CT revealed multiple lung metastases. Paclitaxel and fulvestrant were administered sequentially, the bleeding from the right breast mass stopped and the mass flattened. But, as the tumor progressed, the right breast mass re-enlarged and began to re-bleed. Therefore, hemostatic treatment with Mohs paste was performed in parallel with tamoxifen. Hemostatic effect was observed for a while, but she gradually became refractory to Mohs paste, necessitating frequent blood transfusions. It was decided to discontinue systemic drug therapy and consider palliative treatment, and to perform radiation therapy in parallel with Mohs paste treatment for the purpose of local control. After radiation therapy, the bleeding has completely stopped and blood transfusion has not to be required for 6 months. Although systemic drug therapy has been discontinued at the patient's request, she is still alive. While systemic drug therapy was discontinued, we were able to confirm the pure local control effect of combination of radiation therapy and Mohs paste.

We report a case of sphenoid bone metastasis from breast cancer detected with diplopia, as first site of recurrence. Forty- year-old woman with left breast cancer underwent breast-conserving surgery and sentinel lymph node biopsy. The diagnosis was papillotubular carcinoma, pT1pN0, ER(+), PgR(+), HER2(-). Tweleb years later, the examination of diplopia revealed left abducens nerve palsy for sphenoid bone metastasis from breast cancer. Radiation therapy(a total dose of 36 Gy with VMAT)was administrated as topical treatment, but diplopia did not improve. After that, systemic treatment was performed, and 2 years and 6 months have passed since the recurrence was found, she is still alive. We need to be careful of orbital metastasis as a symptom of metastasis from breast cancer.

A 28-year-old woman realized a left breast tumor. Mammography and ultrasonography revealed focal asymmetric density on the MI area(category 3)and a low-echoic 10 mm tumor with unclear boundaries. We performed an US-guided breast biopsy to confirm the diagnosis. The histopathological examination result suspected nodular fasciitis; however, borderline phyllodes tumor cannot be denied. Tumorectomy was performed under general anesthesia. The final histopathological examination revealed nodular fasciitis due to amplifying fibroblasts with irregular directions. Nodular fasciitis is a benign lesion and sometimes disappears spontaneously. Tumorectomy is often needed to confirm the diagnosis that cannot be identified by needle biopsy. We report a case of breast nodular fasciitis needed to differentiate from borderline phyllodes tumor.

The patient was a 58-year-old woman. She was diagnosed with cT4b, cN3c, cM1, cStage â £, Her2 positive breast cancer with liver, lung and bone metastases. Seven days after the first visit, she came to our hospital for dyspnea. Chest X-ray, chest CT, and echocardiography showed a decrease in EF to 50.6% due to a large amount of pericardial effusion, and she was diagnosed with cardiac tamponade. On the same day, pericardial drainage was performed urgently. The cytopathology of pericardial fluid was malignant, that is to say, she was diagnosed with cancerous pericarditis. Pericardial drainage relieved respiratory distress, and echocardiography showed disappearance of pericardial fluid and improvement of EF up to 80.4%. Docetaxel plus trastuzumab plus pertuzumab therapy was started 10 days after pericardial drainage as first-line treatment. After starting chemotherapy, the response has continued for 6 months without re-accumulation of pericardial fluid.

The patient is a 67-year-old female. She was diagnosed with left breast cancer cT2N1M0, Stage â ¡B, Luminal B-like, and was desided dose-dense AC therapy(ddAC)plus dose-dense paclitaxel therapy(ddPTX)as preoperative chemotherapy. After completing 4 courses of ddAC and visiting to start the first course of ddPTX, she presented with symptoms of fatigue and shortness of breath on exertion. Chest X-ray showed no abnormality and echocardiography showed decreased left ventricular wall motion, leading to a diagnosis of doxorubicin-induced cardiac dysfunction. Preoperative chemotherapy was discontinued and surgery was decided. Two weeks later, CT imaging was performed for preoperative evaluation, which showed the appearance of diffuse pale ground-glass opacity in the bilateral lung fields, and a diagnosis of drug-induced interstitial pneumonia was made. After 3 weeks of steroid treatment, the symptoms improved and the ground-glass opacity disappeared on CT imaging. We were keenly aware that interstitial pneumonia can develop with pale ground-glass opacity that is difficult to diagnose without CT imaging, and that the need for CT should always be considered.

The patient is a 69-year-old female. She was aware of a right breast mass about a year ago, but left it alone. In March 2021, she visited our hospital with a 11 cm mass occupying the right breast and self-destruction due to skin invasion. The diagnosis of invasive ductal carcinoma of the breast(ER-positive, PgR-positive, HER2-negative), cT4bN1M0, Stage â ¢B was made, and preoperative chemotherapy was decided. We expected a high response rate for bevacizumab(Bv)because it was predicted that the skin defect would increase at surgical resection if a response to chemotherapy was not achieved, and in April 2021, paclitaxel(PTX)plus Bv therapy was initiated. After 4 courses, the mass had shrunk to 5 cm and a marked response had been achieved. However, she was unable to continue the treatment due to peripheral neuropathy. Therefore, considering the period of delayed wound healing due to Bv, we decided on AC therapy followed by surgery. In December 2021, Bt plus Ax was performed and the wound could be closed without skin grafting. Since PTX plus Bv therapy is expected to have a high response rate, we considered it to be one of the effective treatment options for locally advanced breast cancer.

Five patients with gastric metastasis from breast cancer were treated in our hospital. About the histopathological types of primary breast cancer, 4 patients were invasive ductal carcinomas and 1 was invasive lobular carcinoma. One patient was found by gastrointestinal fiberscopy for a detailed examination of her high CEA, 2 for stenosis, 1 for bleeding and 1 for epigastralgia. After the diagnosis of gastric metastasis, 2 patients were treated with chemotherapies, 1 with hormone therapy and 2 with palliative treatments. One of them was treated with gastroduodenal stenting for pyloric stenosis, but she was died by bleeding from gastric lesion. Based on the results, constriction and bleeding with gastric metastasis is considered to be severe condition in the treatment of metastatic breast cancer.

A 60s-year-old male, who had laparoscopic partial colectomy with resection of left colic artery for descending colon cancer 8 years ago and completed 5-year-follow-up without the evidence of recurrence, was diagnosed as anastomotic recurrence of descending colon cancer, and referred to our hospital. We planned and safely performed single-incision laparoscopic colectomy(SILC)with intracorporeal anastomosis(ICA)(operation time of 390 min and estimated blood loss of 60 g). Following the adhesiolysis, the intracorporeal resection of the lesion was performed with automatic stapling device preserving middle colic and inferior mesenteric arteries and veins. Then, after the recovery of the specimen, ICA was performed as follows; after making a small hole just below the staple line at the opposite side of mesenteric attachment, the oral and the anal stump of colon was pulled-up and placed side-by-side with temporary strings and automatic suturing device was inserted into the holes and fired to form a side-to-side anastomosis, then the common stab incision was pulled- up with 3 temporary strings and closed with a stapler. The postoperative course was smooth and discharged on postoperative day 8. The ICA can be a good option for SILC when colonic and vascular tension would be the limiting factor of anastomosis.

The patient was a 60's man, whose chief complaints were melena and weight loss. He visited our hospital, and further evaluation revealed rectal cancer(Ra)invading the abdominal wall with multiple liver metastases. The clinical diagnosis was cT4b(abdominal wall)N2bM1a(H1), cStage â £. We performed a transverse colostomy on the day prior to chemotherapy administration. He was administered 8 courses of FOLFOXIRI plus bevacizumab. After the chemotherapy, the primary tumor and liver metastases showed PR, with a diagnosis of ycT3N1bM1a(H1), Stage â £. We performed a robot-assisted laparoscopic low anterior resection for the primary tumor. Two months later, the partial resection of liver S6 and S8 was performed. The patient has been cancer-free for 6 months now.

The patient was a 56-year-old woman. who was aware of a tumor in her left axilla and consulted a nearby doctor. She was referred to our hospital for a detailed examination. No abnormalities were found in the breast by visual inspection, mammography, or breast ultrasound examination. One 29 mm swollen lymph node was found in the axilla. Fine needle aspiration cytology revealed malignant lymphoma; thus, so axillary lymph node excision biopsy was performed, and a diagnosis of axillary lymph node metastasis of breast cancer was made. However, no abnormalities were found. Based on the information presented above, the patient was diagnosed with occult breast cancer cT0N1M0, Stage â ¡A, and breast preservation plus axillary lymph node dissection up to level â ¡ was performed. No metastases were found in the dissected lymph nodes. The treatment policy for occult breast cancer has not yet been established. We report this case with a review of the literature.

The patient is an 85-year-old female who had previously undergone a mastectomy for right breast cancer at the age of 42 years. In September 2020, she visited our hospital with a chief complaint of a chest wall tumor. Physical examination revealed a 3×3 cm ulcerative lesion on the right side of the center chest wall. She underwent a skin biopsy of the tumor under local anesthesia and was diagnosed with a recurrence of right breast cancer(ER positive, PR positive, HER2 negative). PET-CT revealed localized skin thickening on the right side of the sternum and FDG accumulation in the same area, with no other findings suggestive of distant metastasis. Treatment was started with anastrozole and is still ongoing. In this article, we report a very rare case of recurrence 43 years after surgery.

CASE: A 77-year-old woman was referred to our hospital for detailed examination of a cystic liver tumor. Contrast-enhanced CT and MRIshowed a cystic liver tumor with an enhanced mural nodule in S6 of the liver. Under a preoperative diagnosis of hemorrhagic hepatic cyst and mucinous cystic neoplasm(MCN)of the liver, extended posterior segmentectomy was performed. Histological examination of the tumor revealed no neoplastic cells, and the tumor was finally diagnosed as a hemorrhagic hepatic cyst of the liver. CONCLUSION: Similar to previous reports of hemorrhagic hepatic cysts, preoperative differential diagnosis from MCN of the liver was difficult in this case. Hemorrhagic hepatic cysts are rare and are sometimes confused with MCN of the liver, especially when an enhanced mural nodule is found in the cyst. The possibility of hemorrhagic hepatic cysts should be considered during diagnosis of liver cystic tumors.

A 70-year-old woman underwent treatment for cecal cancer(pT4bN1M0, Stage â ¢b)in 2010. Four years and 2 months after the first surgery, she underwent ileum resection for stenosis due to perineal dissemination(P3). Two years after this recurrence, during which time she had completed 26 courses of FOLFIRI plus bevacizumab(Bmab), 9 courses of capecitabine plus oxaliplatin(CapeOX)plus Bmab, and 3 courses of Cape, no peritoneal dissemination was detected by computed tomography( CT). Thereafter, an additional 19 courses of Cape plus Bmab were introduced, but CEA continued to increase. Right ovarian metastasis was suspected based on CT and FDG-PET/CT examination. Four years and 1 month after the initial recurrence of perineal dissemination, the patient underwent bilateral ovarian resection, during which the lack of peritoneal dissemination was confirmed. Pathologically, right ovarian metastasis was diagnosed. The patient is still alive 4 years and 6 months after the first operation.

We describe a case of residual stomach preserving surgery performed under evaluation of residual gastric blood flow with indocyanine green(ICG)fluorography, for gastric cancer with recurrence of splenic lymph node metastasis after distal gastrectomy( DG)in a 65-year-old man. After 4 courses of S-1 plus CDDP(SP)therapy for advanced gastric cancer with ascites, DG, D2 dissection, and Billroth â reconstruction were performed and radical resection was obtained(L, Type 3, pap/tub, ypT3N1H0P0CY0M0, ypStage â ¡B). Three years and 6 months after the surgery, a mass 4 cm in diameter was found in the splenic hilum, and a pancreatosplenial resection was performed to remove the tumor for diagnosis and treatment purposes. We confirmed that there was no problem with blood flow, and we were able to preserve the stomach. Intraoperative ICG fluorescence imaging was considered a promising method for evaluating residual gastric blood flow.

This report describes a case of primary adenosquamous carcinoma of the liver with hepatolithiasis. A 70's man was followed up at a clinic for hepatolithiasis, gallbladder stone, and dilatation of the intrahepatic duct. He visited our hospital for computed tomography(CT)examination. CT showed a 30mm diameter low-density mass in the S2 liver and dilatation of the intrahe- patic duct filled with hepatolithiasis. Blood examination showed elevated levels of tumor markers(CEA 8.0 ng/mL, CA19-9 19,196 U/mL). We diagnosed the tumor as cholangiocellular carcinoma(cT2N1M0, cStage â £A)with hepatolithiasis and performed left hepatectomy and lymphadenectomy. In the specimen, a 39×22mm diameter solid tumor was detected and the intrahepatic duct was filled with haptolithiasis. Pathologically, a mixture of adenocarcinoma and squamous cell carcinoma was observed adjacent to the bile duct. Accordingly, a diagnosis of adenosquamous carcinoma was made(pT3N0M0, pStage â ¢). Multiple liver metastases were detected 8 months after the operation, and chemotherapy was started. He remains alive 11 months after the operation. We experienced a rare case of adenosquamous carcinoma in the liver with hepatolithiasis.

There have been few reports discussing treatments for primary duodenal cancer. In this study, 15 cases of primary duodenal cancer that were treated by curative resection in our hospital between April 2005 and December 2017 were analyzed to study appropriate operative procedures. Prognostic analysis revealed that the median of relapse-free survival and overall survival were 49 months and 74 months, respectively. The 5-year survival rate was 47%. On univariate analysis of relapse-free survival, lymph node metastasis(p<0.01)and post-operative adjuvant therapy(p=0.02)were significant independent prognostic factors. Analysis of the relationship between lymph node metastasis and the depth or location of tumors suggested that pancreaticoduodenectomy with lymph node dissection should be performed to achieve radical resection, since there were some cases that involved lymph node metastasis around the pancreatic head or hepatoduodenal ligament.
