ABSTRACT

Second primary cancer (SPC) is an important prognostic factor for patients with head and neck cancer (HNC); therefore, the association between the prognosis and development of SPC has been well-reported. The use of 2-[18F]-fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET) is valuable to examine cancer stage, evaluate treatment responses and investigate suspected relapses or metastases. In the present study, the case of a male patient who was diagnosed with three primary cancer types, including well to moderately differentiated squamous cell carcinoma (SCC) of the mandible, axillary cutaneous poorly differentiated SCC and prostate adenocarcinoma, was described. Among these, mandible cancer was the first diagnosed when the patient was 70 years of age. Synchronous skin and prostate cancer (PRC) types then developed 3 years later. To the best of our knowledge, this is the first report of the aforementioned combination of cancer types. Postoperative FDG-PET was not performed as no lesions of recurrence or metastases of mandible cancer were found. Three years later, the PRC was asymptomatic and was incidentally detected by FDG-PET performed for a preoperative evaluation of skin cancer. It was indicated that FDG-PET could be utilized in patients with HNC due to there being no accurate FDG-PET protocol to detect SPC over a long-term follow-up.

ABSTRACT

An 87-year-old man, a gardener in Okinawa, first noticed a tumor on the dorsum of his right hand in November 2005. He had been taking prednisolone for the treatment of polymyalgia rheumatica since 2000. A nearby dermatologist incised the tumor for pus drainage in February 2006. In April of the same year, the dome-like tumor reappeared. The same treatment was repeated. Because the culture of the pus revealed fungi at that time, terbinafine hydrochloride and minocycline were administrated under the diagnosis of a deep fungal infection. After a short remission, the tumor recurred in November of the same year and in May and August of 2007 regardless of the repeated incision and pus drainage. He was referred to our hospital on 27 September 2007. His first physical examination at our outpatient office showed a skin-colored, well-demarcated, multilocular, cystic subcutaneous tumor on the dorsum of his right hand. Histopathological examination revealed a pseudocyst with fibrous walls of connective tissue. Continuous, bead-like hyphae, positive with periodic acid-Schiff stain and Grocott stain, were found within the pseudocyst. Morphological and molecular biological examinations of the separately cultured specimens identified the causative agent as Exophiala jeanselmei. The entire cyst was removed under local anesthesia, and an artificial dermis made of silicon membrane was applied to the wound. Skin graft was performed in November after confirming no recurrence of the fungal infection. Terbinafine hydrochloride 125 mg/day has continued. No recurrence has been observed up to now.

ABSTRACT

Linear immunoglobulin (Ig)A bullous dermatosis is a rare autoimmune subepidermal bullous dermatosis caused by circulating IgA autoantibodies directed against the antigens at the basement membrane zone. Most linear IgA bullous dermatosis cases are idiopathic, but some are associated with the use of certain drugs, infections, lymphoproliferative disorders, internal malignancies, autoimmune disorders, collagen diseases or, very rarely, other skin diseases, including autoimmune bullous diseases. Acquired hemophilia is also rare; it is a coagulation disease caused by anti-factor VIII IgG antibodies. Acquired hemophilia has been reported to be associated with malignant tumors, pregnancy or postpartum, drug reactions, collagen diseases such as rheumatoid arthritis, autoimmune disorders, and skin diseases such as psoriasis and pemphigus. We report a case of hemophilia acquired during the course of linear IgA bullous dermatosis and review reported cases of autoimmune bullous dermatoses associated with acquired hemophilia.
