Cutaneous ciliated cyst on the finger: a cutaneous mullerian cyst

As previously recognized by various authors, "cutaneous ciliated cyst" is a confusing term. Typically, the term refers to rare cystic lesions, commonly found on the lower limbs of women in their reproductive years. To date, 40 cases diagnosed as "cutaneous ciliated cyst" have been reported in the literature. Histologically, the cysts are composed of a simple layer of ciliated columnar cells along with nonciliated columnar cells, cuboidal cells, and round "peg-like" cells, resembling fallopian tube epithelium. This histology has been described in cysts found in males and females and in locations other than the lower limbs. Controversy has thus arisen over the etiology of these lesions, with some believing that the cysts arise from heterotopic Mullerian rests and others advocating for ciliated metaplasia of eccrine glands. We herein describe the first case of cutaneous ciliated cyst of Mullerian origin occurring on the dorsal thumb of a 16-year-old female. A review of literature shows that 2 groups of cysts are covered under the umbrella term "cutaneous ciliated cysts." We thus propose the abandonment of the confusing term "cutaneous ciliated cyst" and the adoption of "cutaneous Mullerian cysts" for estrogen receptor/progesterone receptor-positive lesions resembling simple fallopian tube epithelium and "Cutaneous ciliated eccrine cyst" for estrogen receptor/progesterone receptor-negative lesions usually occurring in males, which are immunohistochemically compatible with an eccrine origin.

A case of cutaneous Rhodotorula infection mimicking cryptococcosis

Rhodotorula is a ubiquitous environmental and commensal yeast, and an emerging opportunistic pathogen, particularly in immunocompromised individuals. Clinical infections with Rhodotorula have been increasingly recognized over the past 30 years; however, infections in solid‐organ transplant recipients are uncommon, and cutaneous manifestations have rarely been reported. We describe a 59‐year‐old male renal transplant recipient, who developed cutaneous infection with Rhodotorula upon failure of his graft and commencement of haemodialysis.     

Primary cutaneous endometriosis of the umbilicus: a case report

Cutaneous endometriosis is a rare condition, especially in patients without a history of abdominal or pelvic surgery or known preexisting endometriosis. Most cases present with cyclic pain and bleeding at the site of an umbilical cutaneous nodule correlating with menses. We present an atypical case of primary cutaneous endometriosis of the umbilicus without a prior history of abdominal or pelvic surgery and without cyclic pain or bleeding.     

A case of acute cutaneous graft-versus-host disease mimicking psoriasis vulgaris

Graft-versus-host disease (GVHD) is a frequent complication occurring after allogenic hematopoietic stem cell transplantation and is divided into acute and chronic type. Cutaneous involvement is the most frequent manifestation of acute GVHD, with maculopapular exanthema and perifollicular papular lesions. We describe the first case to develop acute cutaneous GVHD mimicking psoriasis vulgaris shortly after allogenic peripheral blood stem cell transplantation. The patient's rash resembled psoriasis vulgaris and showed histologic features of both psoriasis and acute GVHD. Despite various immunosuppressant therapies, the skin lesion was drug-resistant. Therefore, we administered psoralen-UVA (PUVA) therapy and achieved the desired therapeutic effect. As far as we know, this is the first case of psoriasiform skin eruption as a manifestation of acute GVHD.     

A case of cutaneous bronchogenic cyst over the left scapula.

Bronchogenic cyst is noted shortly after birth or in early childhood and usually presents as a swelling or draining sinus in the presternal area. Its origin and pathogenesis can be explained as a developmental anomaly of the tracheobronchial buds from the primitive foregut. The patient was a 4-year-old boy with a child-fist-sized soft mass over his left scapula, which had been detected at birth and had been gradually growing. Grossly, it appeared to be a simple cyst with clear mucoid fluid. Histopathological study demonstrated a unilocular cyst composed of ciliated pseudostratified columnar epithelia, interspersed goblet cells, smooth muscles, and mucous glands on the cyst wall, which are features compatible with cutaneous bronchogenic cyst.     

Cutaneous ciliated cyst on the cheek in a male

A 53‐year‐old man presented with a 2‐year history of a painless mass on the right cheek. On physical examination, the lump was a solitary, well‐demarcated, mobile lesion. There was no abnormality in the surrounding skin. Ultrasonography demonstrated a single, cystic, well‐defined, subcutaneous cyst, measuring 20 mm in diameter. Laboratory tests, including sex hormones, were within the normal range. The tumor was resected surgically under local anesthesia. The cyst had a slightly yellow wall and contained clear, watery fluid. The patient had no other medical problems and no history of other skin disease. Histopathologically, the unilocular cyst was lined with two layers of epithelium and was devoid of papillary infolding. The inner layer of the cyst was composed of cuboidal to columnar epithelial cells, most of which demonstrated prominent cilia. The outer layer consisted of polygonal cells that contained clear cytoplasm ( Fig. 1 ). No foci of squamous metaplasia were present and the cyst wall did not contain adnexal structures. The inner layer of the epithelium was positive for periodic acid–Schiff (PAS) stain, but contained no diastase‐resistant granules.

Cutaneous ciliated cyst: a case report and histochemical, immunohistochemical, and ultrastructural study

A 19-year-old woman with a cutaneous ciliated cyst on her buttock is reported. Histological, histochemical, and electron microscopic studies revealed ciliated cells, mucinous cells showing merocrine secretion, and areas of squamous metaplasia in the cyst wall. This is the first case of cutaneous ciliated cyst that contained non-ciliated mucinous cells as a component.
