Effect of Pumpkin Seeds in the Treatment of Moderate to Severe Palmar Arsenical Keratosis

Arsenicosis is a major health problem in Bangladesh. Long term exposure of arsenic causes keratosis of palm which reduce working capacity of patient. It also causes massive skin lesions like Bowen's disease which has a risk to develop squamous cell carcinoma. Pumpkin seed is well known for its antioxidant and anticancer properties. So this study will be conducted to identify the compound from pumpkin seeds and to see its outcome on keratosis.

Arsenical keratosis in China: A case report and review of the literature

Review

作者: Wang, Ruojun ; Tao, Rong

AbstractBackgroundArsenical keratosis is a precancerous dermatosis which could be induced by long‐term exposure to arsenic poisoning. Arsenic is often added to traditional Chinese medicine in a non‐compliant manner to increase the effectiveness of psoriasis treatment, which is often the main cause of arsenic poisoning in Chinese patients with psoriasis.ObjectivesWe performed a systemic review of arsenic keratosis during the past 32 years to better understand the sources, treatment, and prognosis of arsenic keratosis in China.MethodsWe searched Medline/PubMed, Embase, CNKI, and Wanfang databases for research studies published between 1992 and 2024. A total of 64 papers with 78 individual Chinese of arsenical keratosis were included in this analysis.ResultsOf the patients included in the analysis, 92.21% of arsenic poisoning was due to iatrogenic factors: Chinese traditional medicine. Seventy‐six patients (98.70%) had skin manifestation of hyperkeratotic papules and plaques, 68 patients (88.31%) had hyperpigmentation, 43 cases (55.84%) had hypopigmentation, and only 4 had a clear indication of Mees' lines in nails. A total of 52.63% of patients presented with tumors, including squamous cell carcinoma, Bowen's disease, and basal cell carcinoma. For patients with tumors, 20 opted for surgery, 6 for radiotherapy, and 3 for PDT. All patients with only cutaneous tumors are currently well‐controlled. Death occurred in one patient with metastatic squamous cell carcinoma. Keratinizing papules improved significantly in 70.59% of patients treated with Acitretin Capsules.ConclusionsIn this study, arsenic sources in Chinese patients were mainly from traditional Chinese medicine, and there were no reports of exposure to water sources or occupational sources in the past 32 years. Most of the patients showed keratinizing papules and pigmentation, and more than 1/2 of the patients showed skin tumors, mainly squamous cell carcinoma. The treatments of tumors are mainly surgical treatment, PDT and radiotherapy can also be selected. The improvement in keratinizing rash was greater than 70% with acitretin capsules. Patients with this disease should be regularly followed up for early detection and timely treatment of potential malignant tumors.

Hematoporphyrin injection mediated photodynamic therapy for secondary squamous cell carcinoma of arsenical keratosis: A case report

Article

作者: Feng, Hao ; Shen, Bo ; Fu, Tao ; Liu, Xiguang ; Li, Linwei ; Ma, Guozhang

Hematoporphyrin injection (HpD) mediated photodynamic therapy (PDT) has demonstrated efficacy in treating various types of Bowen's disease, including basal-cell carcinoma, squamous cell carcinoma, extramammary Paget's disease, and actinic keratosis. We present a case of a male patient who developed squamous cell carcinoma as a result of repeated instances of arsenic-induced keratosis on both his hands and feet. Due to the involvement of the joint in both hands, the patient declined the conventional surgical resection treatment since it could potentially impact normal physiological function. Instead, the patient chose to undergo hemoporphyrin photodynamic therapy. After the treatment, the rash was entirely eliminated and there were no restrictions in the movement of the joint. Nevertheless, a local recurrence was detected throughout the two-year monitoring period. Arsenical keratosis carries a substantial likelihood of recurring. However, we believe that hemoporphyrin photodynamic therapy is effective in treating this condition.
