  • Lymphangioma Circumscriptum of the Vulva- a Case Series Dermatology Section
    DOI: 10.7860/JCDR/2021/47435.14553 Case Series Lymphangioma Circumscriptum of the Vulva- A Case Series Dermatology Section RASHMI S MAHAJAN1, YOGESH S MARFATIA2, ATMAKALYANI R SHAH3, KISHAN R NINAMA4 ABSTRACT Vulval dermatoses pose a diagnostic and therapeutic challenge for the dermatologists. Lymphangioma Circumscriptum (LC) is a form of lymphangioma affecting the skin and subcutaneous tissues that is characterised by benign dilation of lymphatic channels. This uncommon condition is known to occur over the chest, mouth, axilla, tongue, and rarely in the vulva. In this series, authors present three cases of LC of vulva in women between the age group of 45 to 60 years with late-onset fluid-filled lesions over the vulva. The first case had history of hysterectomy prior to onset of lesions, the second case had a spontaneous onset of lesions while the third was a suspected case of pelvic tuberculosis with secondary lymphangioma. Keywords: Lymphangiectasia, Vulvar, Vulval epithelium INTRODUCTION Disorders of vulval epithelium are a confusing spectrum of disorders. They are broadly classified as-1) Inflammatory, 2) Ulcerative and Bullous, 3) Infections, 4) Benign tumours and 5) Malignancies. It is essential to know the exact aetiology to plan successful therapy. LC is a benign lymphatic malformation characterised by dilation of lymphatic vessels in the skin and subcutaneous tissue with lesions erupting locally as isolated or grouped translucid, thin-walled vesicles filled with a clear liquid [1]. These pathological lymphatic malformations have no communication with the normal lymphatics [2]. The precise cause of LC is not established. It could be congenital or acquired as a result of damage to the lymphatic vessels secondary to various aetiologies.

  • Lymphangioma Circumscriptum: Clinicopathological Spectrum of 29
    ORIGINAL ARTICLE Lymphangioma Circumscriptum: Clinicopathological Spectrum of 29 Cases Saira Fatima, Nasir Uddin, Romana Idrees, Khurram Minhas, Zubair Ahmad, Rashida Ahmad, Naila Kayani and Muhammad Arif ABSTRACT Objective: To describe the clinicopathological spectrum of Lymphangioma Circumscriptum (LC). Study Design: Observational case series. Place and Duration of Study: Department of Pathology and Microbiology, AKUH, Karachi, from 2002 to 2012. Methodology: All reported cases of LC were retrieved from medical record. Clinical and pathological features were noted. Frequency percentages were determined. Results: There were 29 cases of LC predominantly males (62%). The mean age was 27.17 ± 15.5 years. The commonest sites was anal/perianal region (24%) followed by extremities (17%) and tongue, (14%). Vulval LC was seen in 3 patients. Two cases were described on scrotum. The lesions were most commonly suspected as viral warts, mole or polyp (in anal region). Vesicles with erosions and bleeding and localized growth were the usual clinical presentations. Four of the patients presented with swelling since birth. All were treated with surgical excision. Microscopic examination revealed acanthotic squamous epithelium with papillomatosis. The subepithelial region had collections of lymphatic channels composed of ectatic dilated vessels with serum and inflammatory cells in their lumina. The lymphatic channels were seen in deeper layers along with lymphocytic aggregates. Conclusion: Lymphangioma circumscriptum is a malformation of abnormal lymphatic channels with feeding cisterns in subcutaneous tissue. It is a benign lesion usually occurring in anal/perianal region and confused with warts. Surgical excision is preferred mode of treatment. Key Words: Cutaneous lymphangioma circumscriptum. Warts. Lymphatic malformation. INTRODUCTION The term lymphangioma circumscriptum was first coined Lymphangiomas are malformations of lymphatic by Morris et al.

Thong2 · Char Loo Tan1,3 Received: 12 July 2018 / Accepted: 18 July 2018 / Published online: 23 July 2018 © Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract A 38-year-old, previously healthy man presented with blood-stained saliva and epistaxis. A 3 mm nasopharyngeal lesion was found. A biopsy was performed and microscopic examination revealed a Kaposi sarcoma. The patient was subsequently found to be positive for human immunodeficiency virus (HIV). The diagnosis of Kaposi sarcoma in the presence of HIV infection advanced his disease to Acquired Immunodeficiency Syndrome (AIDS). Primary manifestation of Kaposi sarcoma in the nasopharynx is extremely rare. The histologic differential diagnosis of Kaposi sarcoma in this unusual site, especially without the clinical history of immunosuppression, is broad. Awareness that nasopharynx can be a primary involvement site of Kaposi sarcoma and serves as index diagnosis of AIDS is important given its serious clinical implication.

    Modern Pathology (2014) 27, S30–S38 S30 & 2014 USCAP, Inc All rights reserved 0893-3952/14 $32.00 Malignant vascular tumors—an update Cristina Antonescu Department of Pathology, Memorial Sloan-Kettering Cancer Center, New York, NY, USA Although benign hemangiomas are among the most common diagnoses amid connective tissue tumors, sarcomas showing endothelial differentiation (ie, angiosarcoma and epithelioid hemangioendothelioma) represent under 1% of all sarcoma diagnoses, and thus it is likely that fewer than 500 people in the United States are affected each year. Differential diagnosis of malignant vascular tumors can be often quite challenging, either at the low end of the spectrum, distinguishing an epithelioid hemangioendothelioma from an epithelioid hemangioma, or at the high-grade end of the spectrum, between an angiosarcoma and a malignant epithelioid hemangioendothelioma. Within this differential diagnosis both clinico-radiological features (ie, size and multifocality) and immunohistochemical markers (ie, expression of endothelial markers) are often similar and cannot distinguish between benign and malignant vascular lesions. Molecular ancillary tests have long been needed for a more objective diagnosis and classification of malignant vascular tumors, particularly within the epithelioid phenotype. As significant advances have been recently made in understanding the genetic signatures of vascular tumors, this review will take the opportunity to provide a detailed update on these findings.

We surveyed 26 tumor-associated proteins in 130 cases, comprising 39 benign vascular lesions (BG), 14 hemangioendotheliomas (HE), 37 KS, and 40 angiosarcomas (AS), by immunohistochemistry. The dominant proteins in KS were HHV8, lymphatic markers, Rb, phosphorylated Rb, VEGF, and galectin-3. Aberrant expression of p53, inactivation of cell cycle inhibitors, loss of beta-catenin, and increased VEGFR1 were more frequent in AS. HE had the lowest Ki-67 index, and the inactivation rates of cell cycle inhibitors in HE were between those of AS and BG/KS. Protein expression patterns in BG and KS were similar. Clustering analysis showed that the 130 cases were divided into three clusters: AS-rich, BG-rich, and KS-rich clusters. The AS-rich cluster was characterized by high caveolin-1 positivity, abnormal p53, high Ki-67 index, and inactivated p27. The KS-rich cluster shared the features of KS, and the BG-rich group had high positive expression rates of galectin-3 and low bcl2 expression.
