ABSTRACT
PURPOSE: The traditional imaging findings reported in Sturge-Weber syndrome (SWS) include endpoints of cortical injury-cortical atrophy and cortical calcifications-but also what has been termed a "leptomeningeal angiomatosis," the latter recognized and reported as a leptomeningeal enhancement on magnetic resonance imaging (MRI). The objective of this study is to demonstrate through neuropathological correlation that the "leptomeningeal angiomatosis" in patients with Sturge-Weber syndrome (SWS), represents a re-opened primitive venous network in the subarachnoid space that likely acts as an alternative venous drainage pathway, seen separately to abnormal pial enhancement. MATERIALS AND METHODS: Retrospective review of MR imaging and surgical pathology of patients that underwent surgery for epilepsy at a tertiary, children's hospital. A pediatric radiologist with more than 20 years of experience reviewed the MR imaging. Surgically resected brain specimens that had been sectioned and fixed in 10% paraformaldehyde for histologic processing, following processing and paraffin embedding, were cut into 5-µm unstained slides which were subsequently stained with hematoxylin and eosin (H&E). Slides were re-examined by a board-certified pediatric neuropathologist, and histologic features specifically relating to cerebral surface and vascularity were documented for correlation with MR imaging of the resected region performed prior to resection. RESULTS: Five patients were reviewed (3 boys and 2 girls; the median age at the onset of seizures was 12 months (IQR, 7 to 45 months); the median age at surgery was 33 months (IQR, 23.5 to 56.5 months)). Surgical procedures included the following: 4, hemispherotomy (right: 2, left: 2) and 1, hemispherectomy (right). A subarachnoid space varicose network was present on both MRI and histology in 4 patients. Calcifications were seen on both MRI and histology in 3 patients. Abnormal leptomeningeal enhancement was present in 5 patients and seen separately from the subarachnoid vascular network in 4 patients. CONCLUSION: Histopathology confirmed the MRI findings of a subarachnoid space varicose network seen separately from leptomeningeal enhancement and presumed to represent an alternative venous drainage pathway to compensate for maldevelopment of cortical veins, the primary abnormality in SWS. No pial-based angioma was identified.

Mammary-type tissue in the vulva was first described in 1872 but has been rarely reported in the literature. This tissue was previously considered as ectopic breast tissue that occurs as a result of incomplete regression of the milk line. Similar to native breast tissue, ectopic mammary tissue is hormone-sensitive and can develop benign changes, such as fibroadenoma, as well as malignant changes. A more recent theory suggests that these benign and malignant mammary-type entities arise from mammary-like anogenital glands, which constitute normal vulvar components. We report a case of a 41-year-old woman who presented with a chronic asymptomatic cyst on the left vulva that eventually became uncomfortable, especially on standing. The cyst was located on the labium minus, measuring 1.0 × 0.5 cm, with no identified erythema or other skin abnormalities. Excision of the lesion and subsequent microscopic examination showed a circumscribed mass with a nodular overgrowth of epithelial and stromal components, resembling a mammary fibroadenoma with pseudoangiomatous stromal hyperplasia. We bring to attention this rare diagnosis and the importance of considering it in the presence of a vulvar lesion. The malignant and recurrence potential of mammary-type tissue necessitates excision with clear margins and close monitoring of these patients.

Pseudoangiomatous stromal hyperplasia (PASH) is a benign breast pathology, which most commonly presents incidentally along with other breast pathologies. The etiology and pathogenesis of PASH are still unknown; however, there is some evidence suggesting PASH is hormone dependent. The clinical history, presentation, and imaging appearance of PASH are variable. Clinically, PASH has a wide spectrum of presentations, from being silent to gigantomastia. On imaging, PASH demonstrates various benign to suspicious features. Here we summarize PASH's clinical presentation, histopathology, imaging features, and management.

BACKGROUND: Pseudoangiomatous stromal hyperplasia is a rare benign breast stromal proliferative lesion of the breast. Clinical presentation ranges from rapidly growing mass to incidental identification in routine screening. This difference in manifestation and its rarity makes it difficult to be a standard treatment protocol. Therefore, we aimed to share our clinical experience in Pseudoangiomatous stromal hyperplasia. METHODS: The files of patients who underwent core biopsy or surgical excision due to a breast mass and resulted in pseudoangiomatous stromal hyperplasia between January 2013 and December 2021 were included in the study. RESULTS: 17 patients with a median age of 37 (22-68) were found Pseudoangiomatous stromal hyperplasia confirmed by surgical excision or core biopsy. Chosen treatment option was observation in 8 patients (47.1%), while surgical excision was used in 9 (52.9%) patients. The mean follow-up period was 55.24 ± 26.72 (13-102) months. None of the patients observed the Malignant transformation during the follow-up period. CONCLUSION: For Pseudoangiomatous Stromal Hyperplasia of the breast, surgical excision with clean margins or close follow-up after diagnosis confirmation by tissue biopsy is sufficient. Pseudoangiomatous Stromal Hyperplasia is not a risk factor for developing breast cancer.

Vascular lesions of the breast are uncommon, however, these are increasingly encountered now due to more frequent use of magnetic resonance imaging. They comprise a spectrum of lesions including benign, atypical, and malignant tumors. The prototype is a hemangioma, which is most often nonpalpable and is detected on routine screening. Different histopathologic subtypes of hemangioma have been described, including perilobular, venous, cavernous, and capillary hemangioma. Other benign vascular lesions include anastomosing hemangioma, a well-circumscribed proliferation of anastomosing blood vessels with lobular or diffuse growth pattern which affects a large segment of the breast, presenting as a painless slow enlarging palpable mass. Recent data suggest that benign vascular lesions diagnosed on core needle biopsy with concordant radiologic and pathologic findings do not require excision and have an excellent prognosis, except angiomatosis, which can be locally aggressive and may recur. The main focus of this study is to present the radiographic, gross, and histopathologic characteristics of benign vascular lesions of the breast and their differential diagnoses.

<b><br>Aim:</b> The study was conducted to systematically analyze the recent peer-reviewed literature related to tumoral pseudoangiomatous stromal hyperplasia (PASH) in males.</br> <b><br>Materials and methods:</b> Articles published in peer-reviewed journals of repute from 2012 to 2023 were evaluated for eight variables: 1) the age of the patient, 2) clinical presentation, 3) laterality (unilateral or bilateral), 4) associated breast disorder, 5) the presence of systemic co-morbidity, 6) imaging modalities aiding diagnosis, 7) treatment, and 8) recurrence.</br> <b><br>Results:</b> There were 10 patients ranging in age from 1 year to 67 years (mean: 34.5 years). In 8 cases (80%), there were breast lumps; in 2 cases (20%), there were axillary lumps at presentation. Pain was not a prominent symptom. Six patients (60%) had another breast disorder at presentation and 3 (30%) had significant systemic co-morbidities, including diabetes and renal insufficiency. The greatest dimension of the lumps ranged from 2 cm to 12 cm, with 80% of the lumps being below 5 cm in size. Imaging modalities utilized in evaluation included breast ultrasound (USG), mammograms, computerized tomography (CT), and magnetic resonance imaging (MRI). All the cases were treated surgically, and the final diagnosis was made only after the analysis of the surgical specimen. Recurrence was recorded in 2 (20%) cases.</br> <b><br>Conclusions:</b> Tumoral PASH is a benign myofibroblastic proliferation disorder rarely reported in males. This condition should be considered a differential diagnosis of breast or axillary lumps, and an evaluation should be initiated accordingly. The recommended course of treatment is adequate surgical excision with regular clinical and radiological follow-up.</br>.

Gynecomastia is a common benign breast disease involving abnormally increased mammary gland tissue that can affect men of all ages. It is usually due to a hormonal imbalance without a definitive underlying cause (idiopathic), or secondary to medications/drugs, systemic disorders, or malignancy. Gynecomastia is often self-limiting, and its management is watchful waiting. Other male benign breast diseases, such as cysts, lipomas, seromas, infections, and pseudoangiomatous stromal hyperplasia, should be worked up in a similar manner and often require surgical drainage or excision.

Cutaneous reactive angiomatosis, a group of disorders defined by benign vascular proliferation, is associated with a number of systemic processes, including intravascular occlusion by cryoproteins. We report a case of a 64-year-old female patient who presented with a 1-year history of nontender petechiae of the bilateral arms and lower legs. Dermoscopic evaluation showed increased vascularity with a globular pattern. Over a period of months, her findings progressed to erythematous to violaceous plaques with admixed hypopigmented stellate scarring of the bilateral lower extremities, forearms, and lateral neck. Biopsy showed increased thin-walled, small dermal blood vessels with focal inter-anastamosis. Some vessels were occluded by eosinophilic globules suspicious for cryoprotein. Subsequent laboratory studies confirmed a diagnosis of type 1 cryoglobulinemia, prompting a bone marrow biopsy that revealed lymphoplasmacytic lymphoma. Herein, we report the fourth case of angiomatosis secondary to intravascular cryoproteins as the initial presentation of an underlying hematologic malignancy. We also present a review of the literature and emphasize the need for thorough initial workup and close and prolonged clinical monitoring for underlying systemic disease in these patients.

Sclerodermatous graft-versus-host disease (GvHD) is one of the many clinicopathological variants of chronic GvHD. One of the rarest forms of this variant is GvHD-associated angiomatosis (GvHD-AA). We describe the case of a 62-year-old male with sclerodermatous GvHD who presented, in consecutive years, two different lesions that showed characteristics of GvHD-AA. The first lesion fitted perfectly with the previously known features of this rare entity. However, the second lesion was more interesting, as the angiomatoid lesion was surrounded by newly appeared adipocytes, something not previously described. The appearance of this peculiar adipose tissue may be explained as related to an important dermal atrophy, as a concomitant appearance of a lipomatous nevus and GvHD-AA, or, finally, as mature adipose tissue related to a previous inflammatory process, that is, lipomatous metaplasia. Both lesions were diagnosed as GvHD-AA, and the second one was considered to be associated with dermal lipomatous metaplasia. We also considered whether hypoxia could be related to both lesions. In the present report, we review previously published cases of GvHD-AA and discuss the different hypotheses that could explain the appearance of metaplasia associated with the second lesion.

The breasts are a common location for diffuse dermal angiomatosis (DDA) in a context of obesity and macromastia. The typical clinical presentation includes erythematous or purplish plaques, reticulated telangiectasias, and sometimes livedo reticularis, often complicated by painful ulcerations of the breasts. Biopsy usually confirms a dermal proliferation of endothelial cells staining positively for CD31, CD34 and SMAa and negatively for HHV8. We report herein a woman with DDA of the breasts presenting as diffuse livedo reticularis and acrocyanosis, both long-standing and considered idiopathic following extensive investigations. Since a biopsy of the livedo did not document DDA features in our case, we suggest that our patient's livedo reticularis and telangiectasias could constitute a vascular predisposition for DDA, as its pathogenesis frequently involves an underlying disease involving ischemia, hypoxia, or hypercoagulability.

RATIONALE: Angiomatosis is a rare non-neoplastic proliferative vascular lesion that typically develops during childhood or adolescence with a female predominance. Management of angiomatosis is challenging because of the manifestation of a wide variety of lesions as well as their invasive and highly recurrent nature. PATIENT CONCERNS: We report the case of a 74-year-old man who presented with a right lower back mass that persisted for a decade. The mass progressively enlarged and had been painful in the previous month. DIAGNOSIS: Computed tomography (CT) revealed suspected lipomatous sarcoma with invasion of the ribs, pleurae, and lung parenchyma. The final pathological examination revealed angiomatosis. INTERVENTIONS: The patient underwent wide composite excision of the tumor along with excision of the pleura and lung nodules in the right lower and middle lobes via video-assisted thoracoscopic surgery (VAST). Fasciocutaneous rotational flap reconstruction was performed immediately after the wide composite excision and video-assisted thoracoscopic surgery (VAST). OUTCOMES: The patient recovered uneventfully, was discharged without complications, and tolerated the daily activities well. LESSONS: Angiomatosis is a rare benign vascular tumor that frequently mimics malignancy. Even if the patient profile does not match the reported epidemiology of this disease, differential diagnosis should be considered. Complete resection is the mainstay of treatment for the prevention of recurrence.

BACKGROUND: Cystic angiomatosis is a rare benign disease presents with multiple lytic and sclerotic bone lesions mimicking a metastatic malignant neoplasia with less than 50 cases have been reported in literature so far. CASE PRESENTATION: We reported a case of a 48-year-old woman who presented to an oncology clinic with multiple lytic and sclerotic bone lesions. Oncologic investigation for metastatic malignant neoplasia started. After that the negative results were obtained by evaluating the primary tumor site, a final diagnosis of cystic angiomatosis was made according to bone biopsy results. CONCLUSIONS: Cystic angiomatosis is a rare disease with unpredictable prognosis. It can mimic metastatic malignancy especially when it presents at old age.

ABSTRACT: The purpose of this paper is to highlight rare highly infiltrative massive Angiomatosis and depict surgical outcome of a rare case series of gigantic lesions in the maxillofacial region. Data were recorded from the medical records of patients. Predictor variables were drawn from demographics, age, gender, site, evaluation of surgical treatment. The outcome variables were the challenges encountered and related complications. Out of 6 patients, the youngest was 10 and the oldest was 26âyears old. Soft tissue and jawbone involvement were seen in 3 patients each with a single massive lesion involving both maxilla and mandible. All 6 patients had wide excision of the lesion with one patient having 2 stage procedures. No complications or recurrence was seen at 1-year follow-up. Angiomatosis is a rare and benign lesion in the head and neck region. its diffuse infiltrating nature may give a false malignant picture. it clinically mimics Hemangioma or Arteriovenous (AV) malformation thus requires thorough evaluation and its surgical intervention is challenging as described in this case series because of its magnitude and infiltrative nature.
