Clinicopathological, dermoscopic features and circumstances of diagnosis of amelanotic or hypomelanotic melanoma: A prospective multicentric study in the French private medical sector.

Background: Amelanotic or hypomelanotic melanomas (AHM) are difficult to diagnose, and are often diagnosed late, with a high Breslow index and a poor prognosis.

Patients And Methods: A total of 226 volunteer dermatologists consulting in private practice in France completed an online form for each new histologically proven case of melanoma diagnosed at their clinic in 2020. This anonymised survey collected data on the clinical, dermoscopic, and histological features of melanoma, as well as the circumstances of diagnosis and initial management.

Angioneurofibroma of Face an Unusual Case: A Case Report.

Neurofibroma may occur as a sporadic solitary lesion or as a part of neurofibromatosis,an autosomal dominant disorder first described by Daniel Friedrich von Recklinghausen in1882. Angioneurofibroma is considered as a new morphological variant of neurofibroma. These lesions can be mixed histopathologically with vascular tumors.

Morphologic Spectrum of Rhabdomyomatous Mesenchymal Hamartomas (Striated Muscle Hamartomas) in Pediatric Dermatopathology.

Background: Rhabdomyomatous mesenchymal hamartomas (RMHs), also termed striated muscle hamartomas, are rare benign tumors of skin and subcutis, which mostly occur at birth with a predilection for the head and neck. Simple surgical excision is the treatment modality of choice with excellent prognosis.

Objective: To review the spectrum of the different clinical and pathologic features of RMHs in pediatric patients and recognize their characteristics to avoid confusion with other lesions in their list of differential diagnosis.

An Unusual Histopathological Presentation of Epidermotropic Metastatic Pharyngeal Squamous Cell Carcinoma.

Epidermotropic metastasis of head and neck squamous cell carcinoma is rare. We report a case of a 56-year-old white man with a history of oral squamous cell carcinoma who presented with multiple papules on the face, eyelid, and chest wall. The histopathologic examination of the skin lesions revealed nests of malignant cells with basaloid features and zones of cytoplasmic vacuolization predominantly within the dermis but focally involving the epidermis.

Clinicopathological and survival analyses of primary cutaneous angiosarcoma in an Asian population: prognostic value of the clinical features of skin lesions.

Background: Primary cutaneous angiosarcoma (CA) is a rare but aggressive tumor with a high rate of local recurrence. This study was designed to analyze the clinicopathological features of primary CA and identify factors of cutaneous manifestations associated with the prognosis of angiosarcoma.

Methods: Medical records of 55 patients with primary CA were retrospectively analyzed to investigate clinical features, survivals, and prognostic factors.

Dual vascular free transverse rectus abdominis myocutaneous flap for hemifacial reconstruction in a vessel-depleted neck.

Cutaneous squamous cell carcinoma (SCC) is the second most common skin malignancy. This report describes the case of an unusual extensive SCC involving the whole hemiface, which required reconstruction with a combination of a dual vascular free transverse rectus abdominis muscle (TRAM) flap and a skin graft. A 79-year-old woman visited our hospital with multiple large ulcerated erythematous patches on her right hemiface, including the parieto-temporal scalp, bulbar and palpebral conjunctiva, cheek, and lip.

Congenital tufted angioma: A multicenter retrospective study of 30 cases.

Background: Recent reports indicate that tufted angioma is a rare vascular neoplasm that manifests more frequently at birth than previously thought. Few studies specifically address congenital presentation.

Objectives: We analyzed the clinicopathological characteristics, clinical course, and treatment of congenital tufted angioma (cTA) and evaluated variables that were indicative of problematic lesions.

[A cutaneous case of angiolymphoid hyperplasia with eosinophilia: Presentation of a rare entity].

We report the case of a Caucasian 73-year-old woman, without medical history, who is operated of two lesions of the forehead and the scalp measuring 0.4 and 1cm. There is no adenopathy.

Masson's tumor of the pineal region: case report.

Intracranial intravascular papillary endothelial hyperplasia (IPEH), also referred to as Masson's tumor, is a condition that rarely occurs in the nervous system. IPEH most frequently occurs extracranially in the skin of the face, skull, neck, and trunk and can easily be mistaken clinically, radiologically, and histologically for angiosarcoma, organizing hematoma, or other vascular malformations. IPEH accounts for roughly 2% of all vascular tumors and is extremely rare intracranially, with only 23 reported cases compared with more than 300 cases of IPEH occurring in the skin and subcutaneous tissue.

Cutaneous angiosarcoma: report of three different and typical cases admitted in a unique dermatology clinic.

Angiosarcoma is a rare and aggressive tumor with high rates of metastasis and relapse. It shows a particular predilection for the skin and superficial soft tissues. We report three distinct and typical cases of angiosarcoma that were diagnosed in a single dermatology clinic over the course of less than a year: i) Angiosarcoma in lower limb affected by chronic lymphedema, featuring Stewart-Treves syndrome; ii) a case of the most common type of angiosarcoma loated in the scalp and face of elderly man and; iii) a skin Angiosarcoma in previously irradiated breast.

Skin diseases of the nose.

Objectives: The goal of this study was to review the main lesion types of the nasal skin and appropriate treatment strategies rather than to present a comprehensive list of all diseases that affect the skin that can involve the nose.

Methods: We reviewed the main nasal skin lesion types and available treatment strategies. Nasal skin lesions were classified as benign, premalignant, or malignant.

Dermoscopic and clinical features of head and neck melanoma.

Background: The dermoscopic criteria of extrafacial melanomas are well-known.

Objective: To determine the frequency of dermatoscopic findings in head and neck melanomas (HNM) and to assess the distinguishing dermoscopic criteria of facial and extrafacial melanoma.

Methods: This observational study included 108 patients with HNM (63% male, mean age 64 years).

Angiosarcoma of the scalp and face: the Mayo Clinic experience.

Importance: The etiology and optimal treatment are unknown for angiosarcoma, an aggressive malignant tumor that affects vascular endothelial cells and can be mistaken for benign lesions such as hemangioma.

Objective: To determine the treatment outcomes of patients with angiosarcoma of the face or scalp treated with a combination of surgery, radiation therapy, and/or chemotherapy.

Design, Setting, And Participants: Retrospective study of 55 patients with angiosarcoma of the face or scalp treated between January 1, 1973, and December 31, 2012, at a tertiary-care academic medical institution.

Blue rubber bleb nevus syndrome: a case report and literature review.

Blue rubber bleb nevus syndrome (BRBNS) is a rare disease characterized by multiple venous malformations and hemangiomas in the skin and visceral organs. The lesions often involve the cutaneous and gastrointestinal systems. Other organs can also be involved, such as the central nervous system, liver, and muscles.

A Recurrent Angiosarcoma Isolated to the Eyelid without the Recurrence on the Primary Lesion of the Forehead.

Angiosarcoma is a highly malignant vascular tumor of endothelial origin. Initially, a cutaneous manifestation presents as a singular or multifocal bruise-like patches on the skin, most frequently on the face, the scalp or the neck regions. On progression, the lesions become violaceous, and ill-defined spongy nodular tumors appear.

Importance: Pseudoaneurysm is a well-known complication of trauma and iatrogenic injury to the vasculature. We report 3 cases of postsurgical pseudoaneurysm after Mohs surgery.

Observations: Three patients who underwent Mohs surgery for nonmelanoma skin cancers presented between 2 and 4 weeks after surgery with several days' history of painful, enlarging, pulsatile subcutaneous masses.

Beneficial effects of early treatment of infantile hemangiomas with a long-pulse Alexandrite laser.

Background And Objective: There is an increasing interest in treating vascular lesions with a long-pulse Alexandrite laser. However, it is difficult to search information in the literature about infantile hemangiomas (IH) treated with long-pulse Alexandrite laser. This article aims to determine whether 755 nm long-pulse Alexandrite laser is effective and safe for early intervention of IH and provides some new data on this issue.

Malignant epithelioid hemangioendothelioma of the lip: a case report and comprehensive literature review.

Malignant epithelioid hemangioendothelioma (MEH), also known as high-risk epithelioid hemangioendothelioma, is a low- to intermediate-grade vascular malignancy originally described as a vascular neoplasm of endothelial origin. This very rare vascular neoplasm has been described mainly in soft tissue, but also in various organs and locations, including the liver, lung, brain, colon, lymph nodes, peritoneum, spleen, bone, skin, heart, soft tissues, and vascular system. Several cases have been described in the head and neck, including the submandibular gland, parotid gland, nasal cavity, parapharyngeal space, maxilla, maxillary sinus, occipital bone, oral cavity, thyroid gland, neck, scalp, larynx, and mandible.

Clinical analysis of an ultrasound system in the evaluation of skin cancers: correlation with histology.

Background: The assessment of skin cancers in the clinical setting is often difficult, with important features such as depth and width remaining unknown until the biopsy with pathology reports are received. When we remove skin cancers, with those especially involving the face, aesthetics and invasion to surrounding structures such as bone and cartilage are important features for deciding the optimal surgical procedure and future reconstructive options. The aim of the study was to compare the accuracy of the ultrasound system in vivo and to correlate the results with the histopathological tumor thickness measured in skin cancer patients.
