Abstract
Canine acanthomatous ameloblastoma (CAA) has been reported to be the most prevalent odontogenic tumor in dogs. The most common location of this tumor is the rostral mandible. Symphyseal-sparing mandibulectomy has been shown to be an effective technique to maintain mandibular continuity and promote early return to function. In this retrospective study, 35 dogs with CAA associated with a mandibular canine tooth were evaluated following a symphyseal-sparing rostral mandibulectomy. Dogs with intraoperative transection of the canine tooth root and subsequent root fragment extraction were included. The objective of this study was to evaluate outcome following excision of CAA with mid-root transection. Data retrospectively evaluated in this study included the following: narrowest tumor margin, narrowest tumor margin at the border associated with the transected canine root, tumor size, and prevalence of local recurrence. This study showed that 82.86% of CAA were completely excised with tumor-free margins (N = 29). The median narrowest overall tumor-free margin was 3.5 mm (interquartile range [IQR] 2.0-6.5 mm) and the median tumor-free margin associated with the border of the transected canine root was 5.0 mm (IQR 3.1-7.0 mm). Follow-up data was obtained in 25 cases via phone interviews with referring veterinarians and clients. No local tumor recurrence was reported in cases with incomplete tumor excision (N = 5). All dogs with follow-up data survived at least 1 year following surgery. It was concluded that segmental or rostral mandibulectomy with wide margins to include the entire mandibular canine tooth with subsequent mandibular instability may not be warranted for dogs with CAA associated with this tooth.

Abstract
INTRODUCTION Oral intravascular papillary endothelial hyperplasia (IPEH) is a rare entity with only 105 cases reported so far. Labial and buccal mucosa are the commonly affected sites. These sites are coincidently subjected to continuous minor trauma, which led the researchers to opine that IPEH could have a traumatic etiology with a further role of fibroblast growth factors. CLINICAL PRESENTATION We report a case of IPEH of right buccal mucosa in a 35 years old South Indian male who clinically presented as mucocele. Histopathologically, multiple lesions were found. Immunohistochemical and histochemical findings have also been presented. DISCUSSION The case is supported by a plausible mechanism involved in the pathogenesis. Thus, IPEH must be included in the clinical differential diagnosis of oral mucoceles and hemangioma. TAKEAWAY LESSONS Being a reactive lesion, it does not require extensive treatment. Clinicians and histopathologists must be aware of this uncommon yet benign condition for appropriate therapy.

Abstract
A 55-year-old male patient with single and well-circumscribed nodule in the lower lip. Accurate diagnosis is based only on histopathological examination using hematoxylin and eosin and immunohistochemical approach, which a large, organized thrombus within the dilated lumen of a poorly demarcated vein, associated with papillary projections of endothelial proliferation occupying vascular spaces. The final diagnosis was intravascular papillary endothelial hyperplasia (IPEH) associated with a thrombus. Oral IPEH is rare and has historically been difficult to diagnose due to its resemblance to other oral lesions. However, the distinctive histological features of oral IPEH associated with a thrombus now allow for its diagnosis through hematoxylin and eosin staining alone, without the need for additional techniques. Therefore, it is crucial for pathologists to be familiar with these unique morphological features to accurately diagnose oral IPEH and differentiate it from more common benign, malignant, or reactive vascular lesions in the oral cavity.

Abstract
Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign non-neoplastic vascular lesion. A typical presentation consists of a subcutaneous nodule that may simulate other clinical entities. Presentation in the oral cavity is uncommon. It is thought to develop as an abnormal proliferative reaction of endothelial cells in a process of impaired thrombogenesis. When endothelial proliferation occurs, a differential diagnosis with a soft tissue sarcoma, in particular an angiosarcoma, should be performed. We report a case of a 68-year-old female patient who presented with a lesion on the upper lip of 3 months' duration. Surgical resection revealed an IPEH. 1 year later, the patient showed a local recurrence requiring excision with clear margins. Pathological and immunohistochemical features can help us distinguish these lesions from those requiring more aggressive treatment. The gold standard is surgical resection with clear margins. Accurate preoperative diagnosis is essential to avoid overtreatment. Emphasis should be placed on clinical, radiological and histological studies.

Abstract
OBJECTIVE Controversial, heterogeneous, and inconsistent responses to beta-blockers have been reported in some cases of infantile proliferative hemangiomas. On the basis of these clinical observations, we aimed to examine the β1 adrenergic receptor (β1-AR) protein expression distribution among different types of pediatric vascular anomalies. METHODS Immunohistochemistry (IHC) was performed for β1-AR on 43 surgical specimens. RESULTS We found positive β1-AR IHC staining in all intramuscular hemangiomas, capillary-lymphatic, lymphatic, venous, and combined malformations, and Masson's tumor cases, as well as in 7 of 10 cases of proliferative infantile hemangiomas. CONCLUSIONS Our research demonstrates, for the first time, the degree of heterogeneous expression of β1-AR among pediatric vascular malformations. Our results support the need for β1-AR assessment in pediatric vascular anomalies to select cases with a robust response to β1-selective blockers. β1-AR assessment may have a strong impact on therapeutic refinement for pediatric vascular anomalies by selecting cases with a stronger response to beta-blockers.

Abstract
Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign lesion that occurs in the soft tissue of any site, including the central nervous system, extremities, head, and female reproductive system. But no case occurred in vagina was reported previously. Here, we report a case of vaginal IPEH in a 54-year-old woman who has a history of radical hysterectomy for endometrial cancer with postoperative radiotherapy. She was positive for high-risk human papillomavirus (HR-HPV) with cytology result as low-grade squamous intraepithelial lesion (LSIL), and pathology from colposcopy-directed biopsy (CDB) presented suspicious high-grade squamous intraepithelial lesion (HSIL). The colposcopy showed an 8mm neoplasm at the right apical angle of vagina. The diagnosis of IPEH was confirmed by biopsy pathology and immunohistochemistry. As the lesion was benign and rather small, we discharged the patient with annual follow-up. The case illuminated that attention should be paid to "HSIL" patients after radiotherapy to exclude the incidence of benign IPEH.
