Article Abstract
Introduction: The clinical appearance of the uncommon cutaneous leiomyomatous tumors (LMT) is nonspecific, leading to an extensive differential diagnosis. A non-invasive tool such as high-frequency ultrasound (HFUS) is required for characterizing LMTs in the clinical setting. Although the sonographic features of their uterine counterpart had been well reported, there are only scant reports on the use of ultrasound for studying leiomyomatous neoplasms of the skin and nail.
Objectives: To identify and well characterize common sonographic features of LMT.
Methods: A retrospective analysis of HFUS images of LMT in three different patients, two of them with multiple cutaneous leiomyomas and another with a subungual leiomyosarcoma.
Results: In all cases, several shared ultrasound characteristics were found. Moreover, we describe a new ultrasonographic sign in cutaneous leiomyomas called the "pine tree" sign, with other features not previously reported.
Conclusions: These ultrasonographic characteristics would strengthen the clinical diagnosis, assist with treatment management, and may help avoid serial biopsies in cases with multiple cutaneous lesions.

Background: Oral leiomyomatous hamartoma (OLH) corresponds to an abnormal, benign and disorganized overgrowth of mature smooth muscle tissue, which can develop in any site where this tissue is found in healthy conditions. The present systematic review aimed to analyze the clinicopathological characteristics of OLH.
Materials And Methods: The protocol of this study was constructed following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and was registered in the Open Science Framework (OSF): OSF.
Gastrointestinal (GI) leiomyomas, particularly those located in the rectum, are extremely rare, accounting for approximately 0.1% of rectal tumors. We report the case of a middle-aged female who presented with chronic diarrhea of unknown origin.
The occurrence of fumarate hydratase-deficient leiomyoma of the abdominal wall is exceptionally rare. A 50-year-old female patient with a past medical history of fumarate hydratase-deficient uterine leiomyoma presented with a left lower quadrant abdominal mass that has been present for the past 2 years. An ultrasound revealed a 3.
Introduction: Angiomyoadenomatous tumor as a nosological entity is not included in the latest version of the International Histological Classification of Kidney Tumors (WHO, 2022) and is related to provisional entity. Currently, there is no consensus among researchers about the nosological affiliation of an angiomyoadenomatous tumor.
Aim: To comparatively analyze the histological, immunophenotypic, ultrastructural and molecular parameters of renal angiomyoadenomatous tumor and clear cell papillary renal cell tumor.
Oral leiomyomatous hamartoma (OLH) is a rare lesion, with only 40 cases reported in the literature. It typically presents early in life as a nodule on the anterior maxillary alveolar tissues or the tongue. Its growth potential is limited, with few cases reaching dimensions >2.
