ABSTRACT
Introduction: Visceral solid cancers can metastasize in almost any organ, including the skin and its appendages. Case Presentation: We report here the case of a 19-year-old Caucasian girl carrying a diagnosis of malignant germ cell tumor of the ovary, with pulmonary and brain metastases, that developed a painful red-violaceous subungual papule of the 4th finger of the left hand, associated with an over-curvature of the nail plate. Dermoscopy was characterized initially by different shades of pink and red, while after few weeks, it showed black pigmentation due to subcorneal hematomas, hemorrhagic crusts, and a rainbow pattern. Histology confirmed a diagnosis of a metastasis from a poorly differentiated carcinoma of ovarian origin. Discussion and Conclusion: A brief review on the diagnosis and treatment of subungual metastases is reported.
ABSTRACT
Stage significantly affects survival of esophageal and esophago-gastric junction adenocarcinomas (EA/EGJAs), however, limited evidence for the prognostic role of histologic subtypes is available. The aim of the study was to describe a morphologic approach to EA/EGJAs and assess its discriminating prognostic power. Histologic slides from 299 neoadjuvant treatment-naïve EA/EGJAs, resected in five European Centers, were retrospectively reviewed. Morphologic features were re-assessed and correlated with survival. In glandular adenocarcinomas (240/299 cases-80%), WHO grade and tumors with a poorly differentiated component ≥6% were the most discriminant factors for survival (both p < 0.0001), distinguishing glandular well-differentiated from poorly differentiated adenocarcinomas. Two prognostically different histologic groups were identified: the lower risk group, comprising glandular well-differentiated (34.4%) and rare variants, such as mucinous muconodular carcinoma (2.7%) and diffuse desmoplastic carcinoma (1.7%), versus the higher risk group, comprising the glandular poorly differentiated subtype (45.8%), including invasive mucinous carcinoma (5.7%), diffuse anaplastic carcinoma (3%), mixed carcinoma (6.7%) (CSS p < 0.0001, DFS p = 0.001). Stage (p < 0.0001), histologic groups (p = 0.001), age >72 years (p = 0.008), and vascular invasion (p = 0.015) were prognostically significant in the multivariate analysis. The combined evaluation of stage/histologic group identified 5-year cancer-specific survival ranging from 87.6% (stage II, lower risk) to 14% (stage IVA, higher risk). Detailed characterization of histologic subtypes contributes to EA/EGJA prognostic prediction.
ABSTRACT
INTRODUCTION: Colonic lipomatosis is defined as a poorly circumscribed, non-capsulated fat accumulation in the submucosal layer of the colonic wall. Clinical presentation varies from asymptomatic to acute surgical complications. PRESENTATION OF CASE: We report the case of a 79-year old male who arrived at the Emergency Department complaining of worsening abdominal pain, fever and nausea. A CT scan revealed a periappendicular abscess extended to the ileocecal valve and also the presence of diffuse intramural fatty tissue of the ascending colon. The patient underwent surgery and a right hemicolectomy was performed. The final histological exam confirmed the diagnosis of gangrenous appendicitis with diffuse abscessualization of the ileocecal valve and the presence of submucosal lipomatosis of the ICV extending to the ascending colon. Patient was discharged at 11th-POD. DISCUSSION: Acute appendicitis can represent a complication, although rare, of colonic lipomatosis. The underlying mechanism can be explained by the obstruction of the stool discharge from the appendix caused by the thickened colonic wall due to lipomatosis. Despite the lack of established guidelines on the management of colonic lipomatosis, surgery remains the preferred treatment in case of acute complications. CONCLUSION: Acute appendicitis is a rare clinical manifestation of colonic lipomatosis. As in the case of other acute complications, such as intussesception, surgery remains the preferred therapeutic approach.
ABSTRACT
BACKGROUND: Case report of a 78-year-old male who came to our observation for a growing pulmonary mass of the left upper lobe without a pre-operative diagnosis. Post-operative histopathology revealed an intrapulmonary Solitary Fibrous Tumour (SFT) of the lung. CASE REPORT: The pulmonary lesion was an ovoid mass centrally located in the left upper lobe; it had been known and stable in size for two years; the last Chest Computed Tomography (CT) Scan highlighted a marked increase in maximum diameter (35 versus 22 mm) with contrast enhancement. In view of the growth of the lesion, the patient was referred for surgery after multidisciplinary team evaluation, although a pre-operative diagnosis had not been reached. The patient underwent Video-Assisted Thoracic Surgery (VATS) left upper lobectomy by a biportal approach. The pulmonary nodule consisted of a proliferation of bland-looking spindle cells intermingled with fibrotic stroma and alternating sclerotic and cellular areas. At immunohistochemistry, the spindle cells expressed CD34, bcl2 and CD99. A final diagnosis of intrapulmonary SFT was reached. The 36-month follow-up was negative for relapses. CONCLUSIONS: Primary intrapulmonary SFTs are extremely rare neoplasms, generally with benign biological behaviour; surgical resection is safe and essential in order to be curative and can be achieved by a minimally invasive approach. Pre-operative diagnosis is challenging, due to aspecific clinical and radiological features. KEY WORDS: Lung, Solitary Fibrous Tumour, Video-Assisted Thoracic Surgery Lobectomy.
