Abstract

Endometrioid adenocarcinoma is one of the most form of common female genital cancer. Recurrences in the laparotomy wound that usually develop in the first year following surgical treatment are rare. Recurrences are more frequently associated to laparoscopic treatment and to advanced stage of malignancy. In literature there are few related works, mainly case reports. Cutaneous recurrences can be treated by surgery, radiotherapy or chemotherapy, according both to clinical conditions of the patient and the presence of other metastatic lesions in different sites. The prognosis of an isolated recurrence is generally favourable. We present a patient affected by uterine fibromatosis, who was surgically treated with hysterectomy and bilateral salpingo-oophorectomy. Three months later, the patient developed in the abdominal scar an adenocarcinoma recurrence, consistent with well differentiated endometrioid neoplasm, referable to a genital cancer. Considering the genital apparatus and supposing a cancer of tiny dimensions, the tubaric origin of the neoplasm is the most probable, due to the fact that, a minor number of sections are usually studied on the fallopian tubes rather than on the cervix and endometrium. The surgical removal of the lesion, followed by chemotherapy and radiotherapy leads to healing. The patient is actually tumor free, 80 months later.

Introduction

Endometrioid adenocarcinoma is the fourth most common gynaecological cancer. It is associated with favourable prognosis [1,2]. Occurrences of laparotomic wound metastases following surgical treatment are rare or just modestly described in literature. Their incidence is evaluated from 1% to 2%, similarly to the incidence of laparoscopic port-side metastases. The rate has been shown to be greater when peritoneal carcinomatosis is found during the primary surgery [3-5]. Recidives mostly occur within 12 months after surgery [6]. The prognosis is related both to the staging and to the treatment of the primary cancer; the prognosis of skin metastases is good if not associated with other localizations, [7].This report presents an atypical case of subcutaneous metastases of endometrioid adenocarcinoma. The patient underwent abdominal extrafascial hysterectomy with bilateral salpingo-oophrectomy, type A according to Queries classification [8] because of a suspected myometrial malignancy. The histological finding revealed cellular leiomyoma with cytological atypia (<10 mitosis x 10 h.p.f.).

Case Report

An 80-year-old, nulliparous, caucasian woman with hypertensive and dyslipidemic disorders underwent a gynaecological examination for abdominal pain associated to irregular bleeding. Her BMI was 28, 1. She reached a physiological menopause in her mid-fifties. The vagina appeared atrophic so the vaginal stenosis did not allow the digital exploration. Completing the pelvic bimanual exam by rectal examination, the uterus was revealed fibromatous and increased in volume. An ultrasound evaluation showed a leiomyoma on the bottom of the uterus of 72 x 71 x 70 mm, and a second infralegamentary myoma on the left of the uterus of 50 x 41 x 55 mm. Both appeared grown by about 20% in dimension during the previous three months. Endometrium was dishomogenous but linear, its maximal thickness measured 6 mm. Pap test, mammography, kidney ultrasound evaluation and the thorax radiography were negative. Hysteroscopic finding was atrophic endometrium, but it was evidenced a severe Asherman syndrome, which hindered an accurate intrauterine study. Suspecting a myometrial cancer, the patient underwent extrafascial hysterectomy with bilateral salpingo-oophrectomy, type a [8]. An abdominal incision was performed according to Kustner’s procedure. No complications occurred during the hospitalization and the patient was discharged 4 days after surgery. The histological examination revealed cellular leiomyoma with cytological atypia (<10 mitosis x 10 h.p.f.) without necrotic areas, cystic endometrial atrophy, ovarian atrophy and chronic salpingitis. Two months later, the patient discovered a painful nodule on the right end of the laparotomic scar port, of about 20 mm diameter. The clinician explained the lesion as a foreign body inflammatory reaction. Because of the nodule’s growing dimension, the patient was referred to our hospital. Six months after the first surgical treatment, an excisional biopsy of the subcutaneous neoformation, measuring 30 mm diameter, was performed.

The histological finding confirmed a subcutaneous localization of well differentiated adenocarcinoma with a cystic papillary structure, endometrioid aspects and moderate mucosecretion. Neither epidermal involvement nor vascular invasion were noticed. Immunohistochemical profile was: CA 125 +; Ck 7 ++; Ck 20 negative; oestrogen ++; progesterone ++; EMA + (Figure 1-5). This result appeared compatible with a genital cancer, with a possible occult primary malignancy. The following abdominal CT scan detected pelvic peritoneal nodes of uncertain meaning. There was no evidence of thoracic lesion at the radiography. The colonoscopy did not identify any neoplastic lesion. The mammography was negative. The PET scan performed one month later discovered a remaining subcutaneous nodule, measuring 10 x 13 mm in diameter, located under the scar of the biopsy, on the right, over the bladder. The patient received external radiation therapy focused on the area of the lesion, (54 Gy – telecobalt-therapy). Moreover, in order to improve the radio sensitivity of the area, chemotherapy with four weekly cycles of cisplatin (40 mg/m²) was concomitantly performed. After 1 month CA 125 and Ca 19.9 were respectively 36, 6 IU7ml and 9, 2 IU/ ml. PET scan supported a clear reduction in dimension of the nodule. The following examinations did not evidence any recurrence of the pathology. After Six years the patient is tumor free.
