Mature teratomas account for approximately 20% of all ovarian tumors identified in pathological studies. Benign or malignant somatic neoplasms developing within teratomas can arise from any tissue in up to 2% of mature cystic teratomas, including low-grade malignant mucinous neoplasms. This report presents the case of a 34-year-old woman with no previous gynecological or general health issues, who was admitted to our Hospital after an asymptomatic pelvic mass was detected during a routine exam. A transvaginal ultrasound revealed a unilateral pelvic mass in the left adnexal region, measuring 8 cm. The CT scan showed a cystic-appearing formation measuring nearly 12 cm, which indented the bladder dome. Final diagnosis indicated a mucinous carcinoma arising from a mucinous borderline lesion within the context of a mature ovarian teratoma. No other involvement or lymphadenopathies were detected on 18FDG-PET CT scan, and the patient is now well and free of recurrences.

Objectives: Although radiologic ground-glass opacity (GGO) components are associated with favorable prognosis, limited evidence supports the prognostic significance of corresponding histologic lepidic components. This study aimed to evaluate the prognostic value of lepidic components in patients with surgically resected invasive non-mucinous lung adenocarcinoma at pathologic (p-) stages I to IIIA.
Materials And Methods: We retrospectively analyzed 352 patients who underwent resection for invasive non-mucinous adenocarcinoma between 2012 and 2016.

Introduction And Significance: Retroperitoneal mucinous adenocarcinoma is a rare malignancy, typically presenting with nonspecific symptoms leading to delay in diagnosis and treatment.
Case Presentation: A 53-year-old man patient was seen with debilitating pain in the right thigh and reduced mobility, following 1 year of recurrent psoas abscesses. The physical exam revealed a mass in the right flank and a positive psoas sign.

Background: Morphological features of tumors can reflect the biological behavior of breast carcinoma; however, a consensus macroscopic classification remains elusive. In this study, we aimed to elucidate the relationship between macroscopic morphology and biological behavior of breast carcinoma.
Methods: We evaluated 328 post-operative breast carcinomas, stratifying them by hormone receptor/human epidermal growth factor receptor 2 (HER2) status (luminal-like, luminal-HER2, HER2-positive [non-luminal], triple-negative), and morphological patterns.

Synchronous mucinous metaplasia and neoplasia of the female genital tract (SMMN-FGT) is a rare disorder defined as mucinous lesions affecting at least two sites in the female genital tract. We report a case of SMMN-FGT in a Caucasian 65-year-old patient with a right adnexal mass. The patient underwent radical surgery and histological examination showed mucinous ovarian carcinoma combined with mucinous metaplasia of the fallopian tube.

Introduction: Pulmonary mucinous epithelioid carcinoma (PMEC) is a rare malignancy that typically progresses slowly and has a favorable prognosis. In contrast, adrenal sarcomatoid carcinoma (ASC) is an aggressive and uncommon cancer with poor outcomes. The coexistence of low-grade PMEC and metastatic ASC is exceedingly rare and presents unique clinical challenges, with limited treatment options and poor prognosis.
