Spindle cell lipoma located in the dermis is uncommon. The plexiform variant of this tumor is rare. In fact, only six cases of this variant have been described previously. We report herein a case of dermal plexiform spindle cell lipoma with prominent myxoid matrix. A 47-year-old male patient presented with a solitary, 2.2 cm-cutaneous mass in the right buttock region that had slowly increased in size for over one year. The dermal lesion was characterized by a mixture of mature adipocytes, spindle shaped cells and inconspicuous ropey collagen bundles in a mucinous background...

A 55-year-old woman presented with a mucopurulent sinusal discharge from the right supragluteal region, with symptoms over the previous five months. This abscess began as a slowly swelling growth, which eventually turned into a discharging sinus, and she was diagnosed with a gluteal abscess. The patient underwent incisional drainage, and intra-operatively, the sinus tract could be seen extending to the retroperitoneum. A subsequent CT scan and an MRI of the abdomen revealed a large heterogeneous retroperitoneal cystic mass on the right side of midline, extending inferiorly into the anterior thigh along the iliopsoas...

Cutaneous mucinoses encompass a variety of cutaneous disorders. Cutaneous focal mucinosis (CFM) was originally described as an asymptomatic solitary lesion characterized by abundant focal cutaneous mucin deposits. However, multiple focal mucinous lesions associated with systemic diseases have also been designated as CFM. Our clinicopathological study of 11 cases of solitary lesions confirmed that CFM is a unique primary cutaneous mucinosis unrelated to mucinosis-associated systemic diseases. We suggest calling this group of CFM lesions "solitary CFM" to distinguish them from multiple CFM associated with mucinosis associated systemic diseases...

INTRODUCTION: Chronic suppurative hidradenitis (CSH) is a benign condition that can affect the perineal region and often leads to the formation of abscesses and fistulas. It is rare for CSH to undergo malignant degeneration into mucinous adenocarcinoma. PRESENTATION OF CASE: We report a case of a 55-year-old male patient with perineal CSH who suffered worsening long-term pain despite multiple surgical procedures to alleviate his symptoms. Pelvic magnetic resonance imaging (MRI) showed multiloculated cystic lesion on the left side wall of the distal rectum with gluteal extension...

A 52-year-old woman was admitted with a 3 weeks history of periorbital edema and lips swelling. She developed several subcutaneous firm erythematous papules and nodules on the face, scalp and two indurated plaques on the upper back and left forearm. These lesions grew rapidly. The patient had a positive history of epileptic seizures since childhood. General examination was normal. There was a mild pitting edema on her hands and feet. Laboratory data were within normal limits. Histopathological examination revealed a well circumscribed accumulation of mucin in the dermis...

Cutaneous focal mucinosis (CFM) is a localized form of cutaneous dermal mucinosis clinically presenting as an asymptomatic skin-colored papule or nodule. The etiopathogenesis of CFM is unclear, but it is thought to represent a reactive lesion. Although trauma has been suspected as a triggering factor, it has never been proven in cases of CFM. We report 2 male patients with trauma-induced CFM arising at the mammary areola, which is an unusual site for CFM. Both male patients presented with a solitary nodular lesion of up to 2 cm in diameter at the right areola...

Cutaneous metastasis of rectal cancer is rare. It typically indicates widespread disease and poor prognosis. We report an exceedingly rare case of rectal cancer with metastasis to the skin and review the literature on cutaneous metastasis of rectal cancer. A 47-year-old man presented with stage IV unresectable adenocarcinoma of the rectum and received palliative chemoradiation for local pain control. About a year later he developed extensive skin lesions involving the genital area, bilateral groin, and perineum...

Folliculosebaceous cystic hamartoma is a distinctive cutaneous hamartoma composed of follicular, sebaceous, and mesenchymal components. The lesions are most commonly found on the face and scalp of young adults, with approximately 30% occurring in the nasal or paranasal regions of the face. The clinical differential diagnoses are extensive and include epidermoid cyst, dermal nevus, soft fibroma, and adnexal tumors including sebaceous neoplasms. Here, the authors present a case of a 24-year-old man who presented for evaluation of an asymptomatic growth on the nose, which had slowly enlarged over 9 years...

INTRODUCTION: Chondroid syringoma (CS) is a rare cutaneous tumor characterized by mixte epithelial and mesenchymal component. The confident histological diagnosis can be obtained by immuno-histochemistry study. Here we present 10 new cases with their clinico-hystological characteristics. METHODS: The 10 cases were observed between January 2000 and august 2013, in Fort-de-France and Louis-Mourier universitary hospitals. For all the cases a controlled histological study was performed by a dermatopathologist expert and immuno-histochemistry was added...

Primary mucinous carcinoma of the skin (PMCS) is a rare cutaneous malignant neoplasm; its regional node metastasis is also rare. Currently, positron emission tomography-computed tomography (PET-CT) is known to be a useful tool to search for early metastatic lesions in various carcinomas. However, PET-CT is not always specific for head and neck lesions because of physiological uptake in the brain, palatine tonsil, salivary gland, thyroid etc. Herein we present two cases of head and neck PMCS in which metastasis was diagnosed accurately by PET-CT...

INTRODUCTION: Perineurioma is an infrequent and benign cutaneous neoplasm characterized by proliferation of perineurial cells. It is classified into two main types: intraneural and the extraneural or soft tissue perineurioma, in which the sclerosing variant is included. Sclerosing perineurioma is more frequently found on acral skin. Clinically, they are well-circumscribed,skin colored, nodular tumors. OBJECTIVE: Describe and communicate clinicopathologic findings from a case series of sclerosing acral perineurioma...

REVIEW
Nancy Cheng, Hadas Skupsky, David S Cassarino
Clear cell proliferations of the skin consist of a diverse group of lesions characterized by the presence of cells with abundant clear cytoplasm. They may arise from primary, metastatic, or non-neoplastic origins, with their distinctive cytoplasmic clearing attributable to causes ranging from artifact to accumulation of materials such as glycogen, mucin, or lipids. Despite the heterogeneity of these lesions, their distinguishing characteristics may be subtle, especially at high power. As such, histologic diagnosis can be challenging, and proper consideration relies on an understanding of the scope of possible origins, etiologies, and key immunohistochemical staining patterns of the various entities...

Plaque-like cutaneous mucinosis (PCM) is a rare disorder of dermal mucin deposition. Some patients with PCM will be found to have an associated malignancy. We report the case of a 72-year-old man presenting with new onset pruritic, waxy-appearing erythematous and skin-colored papules and nodules coalescing into plaques on his shoulder, scalp, and forehead. Skin biopsy revealed cutaneous mucinosis. Despite conservative treatment, his skin lesions progressed, and he was found to have an occult malignancy of pancreatobiliary origin...

Primary cutaneous mucoepidermoid carcinoma remains a rare occurrence. This is the first report of a case of primary cutaneous mucoepidermoid carcinoma originating on the scalp and subsequently metastasizing to the parotid gland. The patient was a 53-year-old female who presented with a purple mass on her scalp since 5 months prior to examination. Histopathology revealed nests and islands of atypical epithelioid cells with pleomorphism, medium to prominent nucleoli, and scattered mucin deposition highlighting with a mucicarmine stain...
