Cutaneous cysts lined by mucinous epithelium are rare entities. We report an unusual case of a 60-year-old female patient who presented with a 2-month history of eruptive cystic papules on her right thigh. Histopathologic study showed multiple, multiloculated cysts located in the dermis lined by nonciliated mucinous epithelium. The cyst lining was positive for AE1/AE3, CK7, CK20, and GCDFP15. Patchy positivity was noted on the p53 stain. Attenuated Sox10 positive cells were identified, raising the possibility of sweat duct origin; however, no myoepithelial layer was identified by p63 staining...

A 44-year-old woman with seronegative polyarthritis presented with a 2-year history of a solitary, bluish-red, oedematous, nonscaly, annular and partially reticulated macule on her right thigh. Histopathological findings revealed perivascular and periadnexal lymphocytic infiltrate in the dermis. Alcian blue and colloidal iron stains highlighted mucinous deposit in the upper and mid dermis. Direct immunofluorescence showed a linear deposit of IgG and C3 along the basement membrane zone. Antinuclear antibody was positive at a titre of 1 : 80, with homogenous and speckled patterns...

We describe three cases of multiple histiocytic cutaneous tumors that began in childhood and affected three members from two generations of the same family: a mother, a daughter, and a nephew. The lesions were mostly skin-colored papules distributed symmetrically on the dorsum of the forearms and hands and on the face and thighs. There were no signs of spontaneous regression. The clinical and histopathological features were consistent with a diagnosis of hereditary progressive mucinous histiocytosis (HPMH), but phenotypic expression varied somewhat between the three patients...

Lupus tumidus is considered a rare subtype of chronic cutaneous lupus erythematosus, characterized by erythema and bright urticarial erythematous-violaceous lesions that leave no scars after regression. Histopathology reveals perivascular and periannexal lymphohistiocytic infiltrates in the papillary and reticular dermis and interstitial mucin deposition. Treatment is based on photoprotection, topical corticosteroids and antimalarials. We report two cases of lupus tumidus, which deserve attention for their low frequency in the literature, in addition to their relevance as a differential diagnosis among dermatologic disorders...

Dermal deposits of mucin in the legs have been described associated with venous insufficiency. However, some degree of stasis dermatitis is generally common in aged individuals. Therefore, some amount of mucin is expected a priori in the reticular dermis of aged patients, even in the absence of clinical lesions. To test this hypothesis, the authors investigated the mucin in the legs of aged individuals without any dermatologic disease. Cutaneous samples were taken from the legs of 15 autopsy cases. A sample of the skin of the legs (either from the left or the right leg without any distinction being made) was randomly taken (without selecting any specific area or attending to macroscopical features)...

A 76-year-old white male with a history of adenocarcinoma of the rectosigmoideum and multiple colonic polyps removed at the age of 38 and 39 years by an abdominoperitoneal amputation and total colectomy, respectively, presented with multiple whitish and yellowish papules on the face and a verrucous lesion on the trunk. The lesions were surgically removed during the next 3 years and a total of 13 lesions were investigated histologically. The diagnoses included 11 sebaceous adenomas, 1 low-grade sebaceous carcinoma, and 1 squamous cell carcinoma...

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...
