1/12. Appendiceal intussusception induced by tubulovillous adenoma with carcinoma in situ: report of a case.Appendiceal intussusception is an uncommon pathologic condition; however, villous adenoma of the appendix is a distinctly rare entity. We report herein a case of appendiceal intussusception induced by tubulovillous adenoma with carcinoma in situ. A 67-year-old man was admitted to our hospital with a 1-year history of lower abdominal pain for investigation. barium enema showed a filling defect with an irregular surface in the cecum, and colonoscopy revealed a cecal tumor with a granular surface. Pathological examination of biopsy samples revealed tubulovillous adenoma with well-differentiated adenocarcinoma, and a diagnosis of cecal cancer in tubulovillous adenoma was made. Surgery was performed and the resected specimen was found to contain a tumor arising from the appendix. The tumor was 5.5 x 4.5 cm in size in the cecal cavity, and the appendix had invaginated into the cecum at its base. The cut surface of the appendix showed the villous tumor filling the appendiceal lumen and projecting into the cecal cavity. Microscopic examination revealed well-differentiated adenocarcinoma in tubulovillous adenoma. To the best of our knowledge, this is the first report of appendiceal intussusception caused by tubulovillous adenoma with carcinoma of the appendix.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/12. Squamous cell carcinoma arising in the skin of a deltopectoral flap 27 years after pharyngeal reconstruction.BACKGROUND: Development of a second primary squamous cell carcinoma in the skin of a flap used for pharyngeal reconstruction is rare. methods: A case of squamous cell carcinoma is presented arising in a deltopectoral flap used to reconstruct the hypopharynx 27 years after total laryngectomy. Three previous reports found on review of the literature are summarized. RESULTS: A second primary squamous cell carcinoma may arise in the skin of a myocutaneous flap in the absence of any obvious risk factors. CONCLUSION: We suspect that long-term exposure of the skin of the flap lining the pharynx to saliva may have been a significant factor in the development of this malignancy. Long-term follow up and awareness of this complication is required for patients with soft tissue reconstruction of the oral cavity and pharynx.- - - - - - - - - - ranking = 6.7823811679493keywords = oral cavity, cavity (Clic here for more details about this article) |
3/12. Hydrotubation for diagnosing carcinoma in situ of the fallopian tube. A case report.BACKGROUND: Primary adenocarcinoma of the fallopian tube is rare and not diagnosed until at an advanced stage. We present a case of carcinoma in situ of the fallopian tube in which cytologic examination obtained by hydrotubation facilitated the diagnosis. CASE: A 55-year-old woman presented to Yamaguchi red cross Hospital for uterine cancer screening. Endometrial brush cytology revealed adenocarcinoma cells, but endometrial curettage showed no abnormal findings. We performed hydrotubation, collecting abdominal fluid by culdocentesis for cytology. The smear test showed adenocarcinoma with cells similar to those obtained by endometrial brush cytology. laparotomy showed no abnormalities in the abdominal cavity, and pelvic washing cytology was negative. Based on the positive cytology found by hydrotubation, we performed a hysterectomy and bilateral salpingo-oophorectomy. Postsurgical histology revealed adenocarcinoma in situ of the fallopian tube. CONCLUSION: The present case suggests that cytologic examination obtained by hydrotubation may be useful in diagnosing early tubal cancer.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
4/12. Intraepithelial G3 adenocarcinoma of the endometrium after tamoxifen treatment.CASE REPORT: In this paper we describe a case of endometrial carcinoma observed in a post-menopausal patient who was treated with tamoxifen for 5 years after a mastectomy for cancer. She came to our department because of vaginal bleeding 2 years after the end of tamoxifen treatment.TREATMENT: She underwent hysteroscopy and a D and C. A polypoid endometrium completely filled the uterine cavity and was carefully removed by curettage; histology showed a highly undifferentiated neoplasia with a component of serous adenocarcinoma, which was likely to originate from endometrial polyps.OUTCOME: The patient underwent radical hysterectomy, but no residual tumor was found in the uterus or in the tubes, ovary, or pelvic nodes, in spite of its low differentiation grade and high potential aggressiveness, and even though the patient was already symptomatic. Two years after surgery the patient is disease free, which is consistent with the evaluation of the surgical specimen, but unusual in poorly differentiated neoplasms.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
5/12. Treatment of carcinoma in situ of the urethra with intraurethral instillations of bacillus Calmette-Guerin. Case report and review of literature.We present the case of a 60-year-old man with carcinoma in situ of the urethra after previous successful radiotherapy of an invasive bladder tumor. Intraurethral instillations with bacillus Calmette-Guerin were given. In spite of initial success, recurrences developed after two courses of 12 intraurethral instillations, and radical surgery was performed. The use of bacillus Calmette-Guerin is reviewed with regard to the locations of superficial transitional cell carcinoma outside the bladder cavity.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
6/12. Virus-associated dysplasia (bowenoid papulosis?) of the oral cavity.We are presenting a case of multifocal, virus-associated dysplasia of the oral cavity. We believe this case represents bowenoid papulosis, which usually is limited to the genital region. The patient, a 21-year-old white man, had recently completed therapy for Hodgkin's disease. An oral examination revealed multiple red 3 to 6 mm macules scattered over the oral mucosa, involving the buccal and labial mucosa, palate, and gingiva. The favored clinical diagnosis was candidiasis. Histologically, the biopsy specimen showed severe epithelial dysplasia. Three additional oral biopsies of different sites were performed and revealed similar histology. Immunohistochemical stains for human papillomavirus were done, and two of four lesions stained positively. Transmission electron microscopy revealed intranuclear viral particles consistent with human papillomavirus. Further questioning and examination of the patient revealed that he had lesions of the penis that were clinically and histologically bowenoid papulosis. In addition, he admitted to oral-genital sex during the period of therapy for Hodgkin's disease. This is the first reported case of oral bowenoid papulosis, and it supports a viral cause for this disease process.- - - - - - - - - - ranking = 33.911905839746keywords = oral cavity, cavity (Clic here for more details about this article) |
7/12. Squamous cell carcinoma of the cervix, with extension in an in situ fashion into the endometrium.A 55-year-old, white, multiparous woman had an invasive, endocervical, squamous cell carcinoma. The tumor had spread superficially into the entire endometrial cavity. The lesion abruptly terminated at the squamocolumnar junction, and the exocervix was free of invasion. Apparently, the cervical, malignant, squamous epithelium had spread upward in a superficial fashion and had mechanically replaced the columnar epithelium.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
8/12. Dissemination of squamous papilloma by surgical manipulation: a case report.The occurrence of multiple squamous cell papilloma in the upper and lower aerodigestive tract is well documented. While apparent inoculation to other areas in the lower respiratory tract at the time of bronchoscopy or tracheotomy is a frequently described occurrence, there have, however, been no reports of transmission of papilloma outside the respiratory tract as a result of surgical manipulation. The purpose of this paper is to report a case of squamous papilloma of the external auditory canal and tympanic membrane which resulted from apparent inoculation at the time of surgery for nasal cavity and nasopharyngeal papillomas together with myringotomies. This supports the hypothesis that an infectious agent, e.g., a virus could be the causative agent and that inoculation to other sites as a result of manipulation is possible. In light of our experience with this case we recommend specific guidelines for the handling of these patients and the protection of surgeons, anesthesia and operating room personnel. Hopefully this report will heighten awareness of papillomas as a potentially transmittable entity to sites outside the respiratory tract, and encourage others to approach these clinical situations with caution.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
9/12. radiotherapy for inverted papilloma: a case report.Inverted papilloma is an infrequent tumour of the nasal cavity and paranasal sinuses associated with controversy. The incidence of carcinoma in situ associated with inverted papilloma, has not been very well documented until now. Therefore, we present a case report characterized by an aggressive clinical behaviour, treated by extensive surgery and ultimately controlled by radiotherapy.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
10/12. Squamous cell carcinoma in situ arising within lichen planus of the vulva.BACKGROUND. lichen planus is a common dermatologic disorder involving the glabrous skin, hair-bearing skin and scalp, nails, and mucous membranes of the oral cavity, penis, and vulva. There have been multiple case reports of squamous cell carcinoma (SCC) developing within lesions of hypertrophic cutaneous lichen planus and erosive oral lichen planus. Recently, there have been several case reports of SCC arising within lesions of the genital mucosa: one case of penile lichen planus, and two cases of vulvar lichen planus. OBJECTIVE. To report a case of SCC in situ developing within erosive vulvar lichen planus. To heighten the awareness, and facilitate the recognition of vulvar lichen planus. RESULTS. We present SCC in situ developing within a lesion of erosive vulvar lichen planus. The patient was treated with simple total vulvectomy by gynecologic surgery. Her vulva remain disease-free 2 years postoperatively. CONCLUSIONS. Vulvar lesions of lichen planus should be recognized and followed closely. In long-standing erosive lesions of the vulva, periodic sampling biopsies should be examined to rule out malignant degeneration.- - - - - - - - - - ranking = 6.7823811679493keywords = oral cavity, cavity (Clic here for more details about this article) |
