Ledderhose disease (plantar fibromas) is histologically related to Dupuytren disease, which has been successfully treated for years with radiotherapy. Many conservative treatments have been advanced for plantar fibromas, including accommodative orthotic devices, which help but do not cure the disease. Surgery is considered the mainstay of treatment for this malady, but the failure rate has been as high as 100%, depending on the type of fasciectomy. Radiotherapy is a new, exciting modality that has shown promising results for treating plantar fibromas.

The clinical differences between odontogenic myxoma (OM) and odontogenic myxofibroma (OMF), and the clinical significance of their classifications, remain unclear. This study reviewed the clinicopathological characteristics of patients with OM or OMF and evaluated the fibrous component of the specimens. Medical records of 21 patients with OM or OMF who underwent tumour resection were reviewed. The percentage of fibrous tissue on the representative sections was evaluated using haematoxylin and eosin- and Masson's trichrome-stained specimens. Histopathological diagnoses included 11 OMs and 10 OMFs with no tumour recurrence except for two cases in which the dredging method was applied. More cortical bone perforation was observed in OM than in OMF cases, without significant differences. Location-locularity and apparent diffusion coefficient value (ADC)-cortical bone perforation were significantly correlated in all OM and OMF cases. The percentage of fibrous tissue in specimens showed bimodal distribution bordered by 45%. There was a significant association between diagnosis based on 45% fibrous tissue criterion and the final pathological diagnosis. Our study showed a tendency for cortical bone perforation in OM compared to OMF and correlation between ADC and cortical bone perforation. According to the histopathological analyses, the fibrous component of each case was bimodal with 45%, which may be a criterion to distinguish between OM and OMF. Accumulating knowledge, such as significant differences in prognosis, may allow for minimal surgical treatment options based on the diagnosis according to this novel histopathological criterion.

BACKGROUND
Papillary fibroelastoma (PFE) is the most common primary benign cardiac tumor. Because PFEs have the potential to embolize, they often are surgically excised. Prior studies have suggested that postoperative recurrence of PFE is rare or does not occur. We aimed to determine the rate at which PFEs recurred after surgical removal and to identify any risk factors associated with recurrence.
METHODS
We retrospectively identified all patients from a single center with pathologically proven PFE, treated from January 1995 through December 2018. Patients were included in the study if they had an echocardiographic examination at least 1 year after surgery. We compared echocardiographic images obtained intraoperatively (after excision) and at dismissal with those of the most recent examination to assess the possibility of PFE recurrence.
RESULTS
We included 98 patients in the study. The mean duration of follow-up was 5.4 (SD 3.7) years (range, 1 to 17); the median duration of follow-up was 4.3 years (interquartile range, 1.9 to 7.7). Twelve patients (12.2%) had echocardiographically supported PFE recurrence. Three patients had the recurrent lesion surgically reexcised, and pathologic analysis showed that two were recurrent PFEs and one was a Lambl excrescence. Initial clinical presentation of stroke or transient ischemic attack was more common for the recurrence group (for the first PFE) than for the nonrecurrence group (83% vs 26%; P < .001).
CONCLUSIONS
Contrary to findings from previous studies, PFEs do recur after surgical excision. These findings emphasize the importance of postoperative follow-up with transesophageal echocardiography for identifying recurrent masses.

Papillary fibroelastomas (PFE) are benign neoplasms, mostly located on valvular surfaces with high embolic potential. This study presents a 27-year single institutional experience on surgical treatment of PFE in an adult patient- cohort with long-term follow-up. This study was approved by the institutional review board. Date and number of IRB approval: 11/23/2017, Institutional Review Board approval number A2014-0149. The need for individual patient consent was waived. We retrospectively evaluated all patients who underwent cardiac surgery for suspected space-occupying lesions in the observation period between June 1991 and June 2018 at our hospital. Clinicopathological features, imaging characteristics, surgical procedures and disease outcome were analyzed. 120 patients were diagnosed with various primary/secondary cardiac tumors and histology confirmed 21 PFEs were found in 16 patients. There was no significant age difference between patients with valvular vs nonvalvular PFEs (P = 0.26). Valvular lesions were found in aortic valve (n = 6), mitral valve (n = 2) and tricuspid valve (n = 1). Nonvalvular PFEs were found in right atrium (n = 2), left ventricle (n = 2), left atrial appendage (n = 2) and aortic wall (n = 1). Valvular lesions were significantly smaller in size compared to non-valvular lesions (P = 0.0013). Left-side PFEs were associated with a high embolization episodes (10/13 patients, 77%) not related to the size. One patient died in-hospital. All other patients were discharged out of the hospital postoperative. Follow-up was performed regularly for a median of 2.8 years (range 0.1-11 years) postoperative. Nonvalvular PFE tended to be larger in size and at least when located on the left sided heart had equally high propensity to embolize compared to valvular PFE. We strongly advocate surgical excision in all left-sided PFE.

Fibro-osseous lesions is a class of diseases with obvious similarities in clinical manifestations and pathological features, which has been attracting the attention of clinicians and pathologists. The latest WHO 2022 Classification (5th edition) included six of these diseases (cemento-osseous dysplasia, segmental odontomaxillary dysplasia, fibrous dysplasia, juvenile trabecular ossifying fibroma, psammomatoid ossifying fibroma and familial gigantiform cementoma) in the " fibro-osseous tumours and dysplasias ", and put forward new ideas on the diagnosis and treatment of these diseases. According to the latest WHO 2022 Classification (5th edition), the clinical and pathological features, diagnosis and differential diagnosis of these six diseases were described.

Review
Calcifying aponeurotic fibroma (CAF) is a very rare benign entity that principally affects the volar fascia, tendons, and aponeuroses of the hands and feet with a peak incidence of between 5 and 15 years, although there have been cases found for a wide age range and at various anatomical sites. We present ten CAF cases; consisting of eight children and two adults. CAF occurred in the extremities in nine of the cases and in the chest wall in one case. CAF ultrasound and radiological findings are nonspecific but may help orientate diagnosis. Magnetic resonance imaging should be performed when there are doubtful cases, when occurring in nontypical sites, and when there are cases of nontypical clinical presentation. Histologically, all cases showed two components, a fibromatosis-like component and a nodular component. Chondroid areas were present in five cases. Calcifications were observed in nine cases. ERG immunostaining showed the same patterns in all the cases; diffuse positivity in pericalcified areas, and patchy positivity in areas away from calcifications. CAF has distinctive histopathological features which should aid in the differential diagnoses with other entities.

OBJECTIVE
Papillary fibroelastomas are associated with an increased risk of embolic strokes. Excision of papillary fibroelastomas may be the primary indication for surgery (primary) or performed during other cardiac operations (secondary). The present study summarizes our experience with primary and secondary fibroelastoma surgery.
METHODS
We analyzed the medical records of patients who underwent surgical excision of papillary fibroelastoma between January 1998 and February 2020. Patient characteristics, indications for operation, tumor size and location, and operative and long-term outcomes were evaluated.
RESULTS
Among the 294 patients (median age: 66 years, 62% female), papillary fibroelastoma was the primary indication for surgery in 136 patients (46%), and 51% of patients had a history of stroke or transient ischemic attack. When papillary fibroelastoma was a secondary indication for surgery (158 patients, 54%), the lesion was identified preoperatively in 39%. Papillary fibroelastomas were located most commonly on the aortic valve and least commonly in the right side of the heart. For valvular papillary fibroelastoma resected from a normal valve, valve shave was sufficient in 96% (196/205). Operative mortality was low in both groups (primary, 0% vs secondary, 2.5%, P = .13), and early neurologic events occurred in 1.3%. Recurrence rate was 15.8% at 10 years. The estimated survival for patients with primary papillary fibroelastoma at 10 years was 78.4%, whereas for secondary papillary fibroelastoma removal it was 53.6% (log rank, P = .003).
CONCLUSIONS
Resection of papillary fibroelastomas can be performed safely, with preservation of the native valve, and with low rates of neurologic events. Operative and long-term outcomes after fibroelastoma resection are excellent.

A 10-month-old boy presented with a 3-month history of progressive left lower eyelid swelling. Examination demonstrated left lower eyelid fullness and hyperglobus with a fatty appearing inferior fornix mass. Imaging showed a mass isointense to fat in the left lower eyelid extending posteriorly, surrounding the inferior oblique with complete fatty infiltration, obscuration of the inferior rectus, and adherence to the globe. The patient underwent orbitotomy with biopsy and debulking of the tumor. Surgical pathology showed multiple fragments of adipose tissue with foci of plump and spindle-shaped cells arranged in bundles and fascicles, consistent with lipofibromatosis. This case illustrates a rare presentation of orbital lipofibromatosis in a pediatric patient.

INTRODUCTION
Connexins are transmembrane channel proteins that interconnect adjacent cells and allow the exchange of signaling molecules between cells and the extracellular milieu. They have been investigated in many tumors to obtain information about tumor nature, behavior, and prognosis.
METHODS
Herein, we present a study on the immunohistochemical expression of connexin (Cx) 43 in 16 cases of atypical fibroxanthoma (AFX). For the immunohistochemical staining, a tissue array was obtained from the paraffin-embedded blocks.
RESULTS
The expression was membranous and cytoplasmic in all cases. Thirteen cases (81.25%) showed strong staining. In the other three cases (18.75%), the staining was medium. None of the cases showed nuclear staining. Fifteen out of 16 cases showed a diffuse pattern, and only one case showed a focal pattern.
CONCLUSIONS
Our results suggest that Cx43 may play an important role in the natural behavior of AFX.
