Five cases with multiple jaw cysts from two families, and two other unrelated patients are presented. Multiple keratocysts of the jaws were found in all patinets whose cysts had been examined histologically. There were also several follicular cysts without keratinization. In some cysts there was even a pronounced proliferation of the basal cells, which resembled basal cell carcinoma. Basal cell carcinomas were seen in only three patients, apparently because the series had been selected for the presence of multiple jaw cysts. However, two patients with only pigmented nevi showed a marked proliferation of the basal cells. An elevation of serum alkaline phosphatase was noted in four out of five patients. The sella turcica was bridged in all but one patient and fusion of the vertebrae was seen in all but two patients. In addition, a high frequency of rib anomalies, frontal and parietal bossing, mild mandibular prognathism and dural calcification was seen. Therefore, what is called the basal cell nevus syndrome may be regarded as a skeletal dystrophy syndrome. Based on the family pedigrees, an autosomal dominant inheritance with poor penetration seems probable.

The inflammatory infiltrate of 5 histologically different types of basal cell carcinoma (BCC) (n = 22) was characterized by means of the alkaline phosphatase monoclonal antialkaline phosphatase technique (APAAP). We proved a distinct stromal pattern of infiltration, which was focally accentuated; in some cases, the cells infiltrated the tumor itself. On phenotyping these cells, we found clear predominance of T cells (75%), which mostly consisted of T helper/inducer cells (45%) and suppressor/cytotoxic cells (32%); in addition, we found B cells (6%) as well as monocytes and macrophages (15%). Morphea-like and adenoid types of BCC showed some tendency to a less pronounced infiltration. Chronic exposure to sunlight and ulceration did not significantly influence the quality or quantity of the inflammatory infiltrate--except for polymorphonuclear leucocytes and macrophages.

A case of metastasising basal cell carcinoma of the skin is presented. The tumour was analysed by enzyme histochemistry and cytology and criteria are set out for establishing the diagnosis of this rather uncommon entity. The lesion is apparently rich in enzymes of the pentose shunt and tricarboxylic acid cycles and shows insignificant acid phosphatase activity and no activity of alkaline phosphatase. These enzyme histochemical findings are thought to be important in the differential diagnosis of various types of tumour.

Basosquamous carcinoma (BSC) is a rare type of malignancy with features of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) with a potential for aggressive behaviour infiltration and destruction. First reported by MacCormac in 1910 in a series of rodent ulcers, this entity does have an increased risk of recurrence and metastases as well, which distinguish it from other forms of basal cell carcinoma. The overall incidence of basosquamous carcinoma ranges from 1.2% to 2.7%. An unusual case of basosquamous carcinoma (BSC) is presented where 18- fluorodeoxyglucose positron emission tomography ((18)F-FDG-PET) scan diagnosed unsuspected extensive metastatic disease in the bone marrow, which was further proven histopathologically. The patient was a 32 years old man with history of recently diagnosed basosquamous carcinoma of left cheek involving left lower eyelid and left eyeball. Contrast enhanced computed tomography(ceCT) of the head and neck demonstrated involvement of the left cheek skin by the malignancy along with erosion of zygomatic bone and phthisis bulbi of the left eye. The serum alkaline phosphatase was elevated (255units, normal range 50-150units). The patient was referred for (18)F-FDG PET, for disease status evaluation. The scan showed intense tracer uptake in the left zygomatic region, the site of known primary disease. Intense tracer uptake was noted in the multiple lesions of bone marrow of axial as well as appendicular skeleton. The scan appearance was highly suggestive of metastatic bone marrow involvement. A bone marrow biopsy was performed to confirm the scan findings. Guided by the (18)F-FDG PET scan findings, bone marrow biopsy was performed and metastatic basosquamous carcinoma was diagnosed. We believe this is the first reported case of basosquamous carcinoma where extensive metastatic bone marrow disease was diagnosed with the aid of (18)F-FDG PET. At first diagnosis, an advanced stage of BSC is often present. Due to its metastatic potential, extensive primary surgical resection of BSC, possibly completed by radiation or photodynamic adjuvant treatment is recommended. Given the aggressive nature of basosquamous carcinoma, whole body (18)F-FDG PET is very useful in diagnosing metastatic BSC. In conclusion, this is the first reported case of the use of (18)F-FDG PET study for diagnosing metastatic bone marrow disease in a patient with basosquamous carcinoma.
