Apocrine gland adenocarcinoma in a persian cat remission with homeopathic treatment: case report

Apocrine gland carcinomas are rare malignant neoplasms that occur in cats. Available treatment is surgical, would lead to total ablation of the external acoustic meatus and usually recurrent [1,2].Methodology:In December 2020, a homeopathic consultation of the feline, male, Persian, 13 years old, a history of the disease was reported, which started in 2015, adding up to six recurrences of tumor processes in the eyelids and recent formation in the left ear canal.The result of the histopathological examination confirmed apocrine adenocarcinoma.Prior to homeopathic treatment, tumors recurred despite surgical interventions and prophylactic treatment with trichloracetic acid.However, remaining formations were noted in the eyelids and ear canal. It has a rounded blackened shape in the upper right eyelid measuring 0.4 cm and the lower 0.2 cm, round. In the left ear canal, around 1.6 cm, in addition to 4 points scattered in the ear folds. Homeopathic treatment was started for two months with Arsenicum album30 cH, twice a day; Carcinosinum 200 cH, once a day, and complex containing Avena sativa4 cH, Echinacea angustifolia4 cH, Conium maculatum6 cH, Thuja officinalis6 cH and Silicea terra6 cH, four times a day. Every two months, the clinical picturewas reassessed, potenciesand frequencies readjusted.In a few months,there was complete remission of the tumor, recovery of welfare, and improvement in mood and appetite. The free and informed consent term was signed. There was no recurrence of tumors until May2022. Conclusion:This study proved to be effective, documented with photos and exams. Approaching a rare case may provide a new therapeutic possibility. The credibility of quality homeopathic case reports has been increasing due to methodological requirements using tools developed in recent studies.

A Case of Apocrine Adenocarcinoma of the Upper Eyelid

PURPOSE: To report a case involving an eyelid mass that was diagnosed as apocrine carcinoma. CASE SUMMARY: A 52-year-old man visited our hospital with a recurrent mass on his right upper eyelid, which had developed 4 years prior. Initially, he received laser therapy at a dermatologic clinic to remove the mass. Two years later, the mass recurred and was excised at another clinic. At the time the patient visited our institution, the lesion had developed into multiple erythematous nodules at the margin of the right upper eyelid. The results of excisional biopsy performed under local anesthesia revealed hidradenoma papilliferum. One month after excision, recurred multiple elevated nodules were found at the margin of the excision, and thus total excision of the mass and reconstruction of the upper eyelid was performed. Biopsy confirmed that the mass was apocrine adenocarcinoma. Five months have passed since the excision and no evidence of recurrence has been observed. CONCLUSIONS: Apocrine adenocarcinoma is a malignant tumor of the sweat gland and is rarely found on the eyelid. Apocrine adenocarcinoma should be considered in the differential diagnosis of recurrent eyelid mass at the eyelid margin.

A Case of Apocrine Adenocarcinoma associated with Basal Cell Carcinoma / 대한피부과학회지

Apocrine adenocarcinoma is rarely reported in the world and only 4 cases are reported in Korean literature. We encountered a case of apocrine adenocarcinoma associated with basal cell carcinoma in a 76-year-old female. Excisional biopsy showed well demarcated basophilic cell mass in the upper dermis and glandular structure in the lower dermis. Basophilic cell mass consisted with basaloid cells and had peripheral palisading arrangement. Glandular structures characterized by cells with abundant eosinophilic cytoplasm showed decapitation secretion. The cells showed nuclear atypicality, plemorphism and prominent nucleoli. The cytoplasm contained PAS-positive, diastase-resistant granules and stains for lysozyme and GCDFP-15(Gross Cystic Disease Fluid Protein-15) were positive.
