RESUMEN
Typically, local spread and lymph-vascular space invasion (LVSI) occur before lymph node (LN) and distant metastases during the progression of uterine cervical cancer. The prognostic value of LVSI in cervical superficially invasive squamous cell carcinoma (SISCC) is still debated. We encountered a rare case of cervical SISCC without LVSI presenting with multiple LN metastases, including pelvic, para-aortic, and left supraclavicular LNs. Immunohistochemical analysis of p16 and in situ hybridization of human papillomavirus confirmed the relationship of the cervical SISCC and pelvic LN metastases. Aspiration cytology of the left supraclavicular LN showed squamous cell carcinoma and our final diagnosis was uterine cervical squamous cell carcinoma, stage IVB. The patient underwent adjuvant chemotherapy. Although relapse was observed at the vaginal stump and in pelvic and para-aortic LNs, chemotherapy and radiotherapy were effective. The patient is alive without disease 40 mo after initial treatment. This is the first case report of cervical SISCC without LVSI presenting with supraclavicular LN metastasis, which contributes to our understanding of the value of LVSI. Immunohistochemical analysis of p16 and in situ hybridization of human papillomavirus were useful in confirming the relationship of cervical SISCC and its metastases. As cervical SISCC with LN metastasis is rare, multi-institutional joint research is needed to clarify its prognosis and appropriate treatment.

AIM: To evaluate factors related to the occurrence of Sheehan syndrome. METHODS: The obstetrical disseminated intravascular coagulation score, total volume of hemorrhage, shock index, level of consciousness at the time of shock occurrence and pituitary magnetic resonance imaging findings were evaluated in nine women who showed massive hemorrhage during delivery. These clinical outcomes were analyzed in all these patients who were prospectively followed-up to identify any possible occurrence of Sheehan syndrome. RESULTS: Compared to six women with non-Sheehan syndrome, three women who were diagnosed with Sheehan syndrome showed significant elevation of the obstetrical disseminated intravascular coagulation score, decrease in the level of consciousness during shock and remarkable pituitary gland atrophic change with an empty sella turcica detected by pituitary magnetic resonance imaging. The volume of hemorrhage during delivery and shock index were not significantly different between these two groups of women. CONCLUSION: Careful attention and follow-up should be paid to women with post-partum massive hemorrhage for early detection and management of women with Sheehan syndrome.

AIMS: Genomic instability has been indicated during the dedifferentiation process from leiomyoma (LM) to leiomyosarcoma (LMS). Previously, we have described that nuclear expression pattern of DNA damage response protein p53-binding protein 1 (53BP1), detected by immunofluorescence, reflects the magnitude of genomic instability during malignancy. Here, we present a case of LMS arising from LM with molecular analysis of 53BP1, which showed transitional magnitude of DNA damage response within a tumor. METHODS AND RESULTS: A fifty-year-old female with abdominal mass underwent hysterectomy. Histologically, the tumor consisted of LMS with highly atypical multinucleated giant cells as well as an LM component with transitional atypical spindle cells in the border area. LMS showed diffuse nuclear staining of 53BP1 expression, which has been previously described as high DNA damage response pattern. In contrast, the LM component lacked 53BP1 immunoreactivity and focal expression was observed in transitional lesion. Furthermore, double-labelled immunofluorescence revealed co-localization of 53BP1 with p53 and Ki-67 in the LMS component, which indicated abnormal DNA damage response in proliferative state. CONCLUSIONS: This study revealed that diffuse-type 53BP1 expression may be beneficial to estimate genomic instability during dedifferentiation from LM to DLMS.

BACKGROUND: Mitotically active cellular fibroma (MACF) of the ovary, characterized by relatively high mitotic activity without severe atypia, represents a relatively new disease entity. MACF is categorized as a benign ovarian tumor. However, due to a limited number of case reports, its clinical and pathological features and optimum management remains largely undetermined. Herein, we report on a rare case of MACF that grew rapidly in size and was diagnosed on detailed pathological examination. CASE PRESENTATION: A 44-year-old Japanese woman, who detected a myoma-like lesion 1-year earlier, was referred to our hospital when the follow-up examination demonstrated that the mass had increased in size. Magnetic resonance imaging revealed a T1 isointense and T2 hyperintense tumor (11 cm in diameter) in the right pelvic cavity. Laparoscopy confirmed the presence of a right ovarian tumor and laparoscopic right adnexectomy was performed. The tumor cells consisted of dense cellular proliferations of spindle fibroblast-like cells without significant cytological atypia. The mitotic activity index was estimated at >15 mitotic figures per 10 high-power fields. Reticulin staining and FOXL2 mutation analysis excluded the possibility of an adult granulosa cell tumor, and the patient was diagnosed with a MACF of the ovary. CONCLUSIONS: To the best of our knowledge, we are the first to report on a case of rapid growth of a MACF of the ovary during follow-up. When an increase in the size of a solid ovarian mass is detected, a MACF should be considered as a differential diagnosis.
